From what I've learned from my textbooks and in class lecutures it seems that inducing angiogenesis for people with severe burns would be an excellent way to speed up the healing process. Is this already being done? If so or if not what are (if any) challenges that are presented to doctors and surgeons trying to use this self-healing method?
Adipose tissue angiogenesis as a therapeutic target for obesity and metabolic diseases
Current pharmacotherapeutic options for treating obesity and related metabolic disorders remain limited and ineffective. Emerging evidence shows that modulators of angiogenesis affect the expansion and metabolism of fat mass by regulating the growth and remodelling of the adipose tissue vasculature. Pharmacological manipulation of adipose tissue neovascularization by angiogenic stimulators and inhibitors might therefore offer a novel therapeutic option for the treatment of obesity and related metabolic disorders. This Perspective discusses recent progress in understanding the molecular mechanisms that control adipose tissue angiogenesis and in defining potential new vascular targets and approaches for the treatment of this group of diseases.
Angiogenesis and inflammation are host-dependent hallmarks of cancer that can be targeted using prevention approaches long before tumours initiate and progress
Several prescription and non-prescription drugs are already available for use in angioprevention, as well as a growing array of nutraceuticals
We propose four levels of angioprevention: I for the 'healthy' population II for patients with increased risk of cancer III for preneoplastic lesions and IV for prevention of cancer recurrence
There are several successes in cancer prevention that demonstrate clinical feasibility and levels of intervention, from no to little to intense physician involvement
To avoid toxicity while maintaining efficacy, angioprevention needs to achieve a degree of angiogenesis control that is not excessively suppressive, such that healthy vascular function is maintained

Having originally trained in medicine at Trinity College Oxford, where he gained a first class degree, Professor Stebbing completed junior doctor posts in Oxford, and then undertook training and a residency programme in Internal Medicine at the John Hopkins Hospital, Baltimore, returning to London to continue his career in oncology at The Royal Marsden and then St. Bartholomew’s Hospitals. Professor Stebbing’s original PhD research investigated the interplay between the immune system and cancer he was appointed a senior lecturer in 2007, and a Professor in 2009.
Professor Stebbing has published over 600 peer-reviewed papers, as well as writing regularly for national newspapers and presenting new data on optimal cancer therapies at major international conferences. His focus is on new therapies in cancer, and the systemic management of patients with solid malignancies including a number of new biomarker-based approaches, with an emphasis on circulating tumor cells and cell free DNA. His laboratory work is concentrated on these areas including new druggable target discovery and gene regulation examining the role of non-coding RNAs in stem cells. The charity Action Against Cancer www.aacancer.org has been set up to support Justin’s work which concentrates on drug development and has the ambitious goal of developing cures.
Professor Stebbing is a Fellow of the Royal College of Physicians, the American Board of Internal Medicine and the Royal College of Pathologists, and sits on the Advisory Boards of a number of international cancer committees. He chaired the World Vaccine Congress and currently Chairs the Irish Cancer Society oversight committee he was awarded the Silvia Lawler prize in 2015. Justin’s team published in Nature Medicine the discovery of a new cancer-causing gene which has now been implicated in breast, gastrointestinal, lung, and other solid tumors, and a drug development programme around this is underway. The National Institute for Health Research (NIHR) awarded Justin Stebbing its first translational research professorship in oncology, aiming to bridge the gap between the laboratory and the patient to ensure therapy is personalized. The focus of this is understanding why some patients with cancer relapse, and developing a program to reverse this and prevent it. Recently, Professor Stebbing was elected to the American Society for Clinical Investigation.

Sir Roger Moore (1927-2017) was a special advisor and friend to the Angiogenesis Foundation, starring in an advocacy video and working to raise awareness for disease-related vision loss.
Sir Roger’s professional accomplishments were extraordinary and well-documented. He will forever hold an enduring place in the history of cinema, through his portrayal of James Bond from 1973-1985, the longest serving actor in the role of Special Agent 007. Sir Roger made his Bond debut in 1973 in Live and Let Die and continued for a total of seven productions. Trained at the Royal Academy of Dramatic Art and Cambridge Arts Theatre, he began his acting career on stage in London’s West End and then on Broadway. He subsequently headed to Hollywood where he worked at MGM and Warner Bros. Studio. Notable roles include his work in the television series Ivanhoe, The Alaskans, and Maverick. His breakout role was as Simon Templar in the most successful television series of its time, The Saint. Then followed his widely popular portrayal of Lord Brett Sinclair in The Persuaders, with Tony Curtis as his co-star. Sir Roger also wrote a handful of books, among them My Word is My Bond: A Memoir, Bond on Bond and Last Man Standing.
Sir Roger was an internationally celebrated humanitarian. For over 25 years, he worked with UNICEF, appointed as Special Ambassador in 1991 and as Goodwill Ambassador in 1999, to advocate for the rights of children. Queen Elizabeth II recognized Sir Roger’s charitable contributions in 1999 by appointing him a Commander of the Order of the British Empire (CBE) and, again in 2003, when she made him a Knight Commander of the Order of the British Empire (KBE).

George W. Thorn was an electric figure in medicine. At the age of 36 he burst on the scene at Harvard Medical School in 1942 as the ninth Hersey Professor of the Theory and Practice of Physic and the third Physician in Chief of the Department of Medicine at the then Peter Bent Brigham Hospital. Frequently mistaken for a medical student or resident, he remained youthful in outlook and appearance until his 90s. He died on 26 June 2004 at the age of 98.
George made vital contributions to the clinical use of adrenal steroids. He began his career in endocrinology as a medical student at the University of Buffalo, went on to Ohio State and then joined the faculty at Johns Hopkins where Harvard found him.
The Brigham, as it was called, was then a Dickensian institution as were all of the Harvard hospitals of the mid 20th century. Built in 1914, its design was inspired by a fear of hospital borne infection. The four 30 bed male and female surgical and medical services were wide open, poorly ventilated and over-heated pavilions separated from each other by a long corridor that was still partially open to the elements well into the 1950s. Flimsy curtains separated the ancient beds. Privacy was non-existent. So called semi private beds were on a floor above.
They were located on open wards as well, but those patients were the private patients of staff members, while the large first-floor pavilions were the provinces of the house staff. A three floor private service was housed near the pillared entrance of the hospital. It was scarcely lucullan in its appointments, but there the tired interns could make a decent breakfast for themselves on Sunday mornings.
Laboratories at the old Brigham were primitive by any standards. One small old building housed the hematology, chemistry and pathology labs as well as George’s endocrinology lab and a few beds where patients with endocrine disorders could collect urine and undergo various hormone tests. It was an early form of the later General Clinical Research Centers based on the Rockefeller University Hospital model. A horribly ventilated and totally inadequate animal facility was in the basement.
Despite lack of space and money, George conjured up a full time staff of investigators. His own program in endocrinology produced George Cahill and Albert Renold among many others. His many contributions to the endocrinology literature included over 400 papers.
To expand the academic department of medicine he focused first on cardiology. He was wise enough to build on the clinical greatness of Samuel A. Levine and added the cardiac catheterization skills of Lewis Dexter and, later, Dick Gorlin. Frank Gardner came from the Thorndike laboratory at the Boston City Hospital to run hematology. He attracted house staff of the quality of Don Thomas and Clem Finch and scores of others who became leaders of academic medicine. George’s greatest gift was free floating imagination. His discussions of patients on rounds were always brilliant if occasionally somewhat off base. A favorite resident told me “You listen—I will not. Then when he is gone—we’ll do it my way.”
Armed with that creative style, Thorn dissuaded John Merrill from a career in cardiology to lead an effort in renal dialysis and transplant. The renal transplant program at the Brigham became world-renowned. He was instrumental in the formation of the Harvard-MIT program in Health Science and Technology, and he was the first scientific leader of the Howard Hughes Medical Research Institute. But his free flowing thought processes and his youthful, friendly personality were sometimes confusing. One inadequate resident once boasted that George had appointed him to the Chief Residency when actually George had fired him!
In his later years as the Chief of Medicine, George began to worry about how to elevate the role of basic science in a department of medicine and how to prevent specialists from forgetting general medicine. He wrote two very important articles on those subjects in the New England Journal of Medicine. Whether one agrees with them or not, they are well worth reading today.
George’s last appointment was: Physician in Chief, Emeritus, Brigham and Women’s Hospital, Hersey Professor of the Theory and Practice of Physic, Emeritus & Samuel A. Levine Professor of Medicine, Emeritus, Harvard Medical School.

Dr. Giannoula Klement, an internationally recognized expert on tumor angiogenesis and antiangiogenic therapy, worked with Judah Folkman elucidating the role of platelets in angiogenesis and their possible role as biomarkers in the early detection of cancer and tumor recurrence. Because the majority of angiogenesis regulatory factors appear to be sequestered in platelets, which possess the ability to selectively accumulate these factors in patients with cancer, they have the potential to detect tumor growth before it is clinically apparent.
Dr. Klement trained with another angiogenesis pioneer, Dr. Robert Kerbel, and with him co-authored a number of papers on antiangiogenic therapy for cancer and the mechanisms of tumor escape from these agents. Dr. Klement received her M.D. from McMaster University, Canada, and did her residency at the Hospital for Sick Children at the University of Toronto, Canada.

Nobel Laureate in Physiology or Medicine 1963
Nobel Prize Winner in Medicine. A physiologist, he was honoured in 1963 for elucidating the chemical and mathematical processes involved in nerve impulse conduction. Born to a family distinguished in both the literary and scientific worlds (his older half brothers included biologist Sir Julian Huxley and “Brave New World” author Aldous Huxley), he was exposed to advanced learning from early childhood and was educated at the University College School and at Westminster before earning a scholarship to Trinity College Cambridge where he studied biology, physics, and physiology.
Upon graduation he partnered with Sir Alan Hodgkin in a series of experiments which involved passing a wire down the long axis of a large neuron taken from a giant Atlantic squid and measuring electrical voltages along the nerve membrane. The two men published their observations in a small article in the journal “Nature” but soon found their work interrupted by the outbreak of World War II. During the conflict Sir Andrew performed anti-aircraft and naval gunnery research then in 1946 resumed his neurophysiology studies. Though it was long known that potassium ions (K+) could pass thru a neural membrane it was felt that sodium ions (Na+) could not Sir Alan and Sir Andrew were able to demonstrate that during the excitation or rising phase of a nerve impulse Na+ ions diffuse into a cell while in the falling phase K+ ions pass out and were to propose the Hodgkin-Huxley Model, a series of differential equations that explain and quantify how the action potentials of neurons are initiated and propagated.
Finishing the work that was to lead to the Nobel Prize around 1952 Sir Andrew maintained his professorship at Cambridge, turned to the subject of muscle contraction physiology, and was elected Fellow of the Royal Society in 1955. From 1960 thru 1969 he held a faculty position at University College London and in 1963 received the Nobel Prize along with Sir Alan and Sir John Eccles, an Australian who had independently studied similar subject matter. He was to lecture at major institutions on both sides of The Pond, occasionally drawing fire for publicly conceding that Darwin’s Theory does indeed have holes and that some things such as consciousness cannot be explained by evolution.
Knighted in 1974, he received the rarely bestowed Order of Merit (OM) in 1983 and from 1980 thru 1985 was President of the Royal Society, in 1983 upholding, in the face of numerous letters of protest, the group’s election of Prime Minister Margaret Thatcher. In 1984 he was to succeed Sir Alan as Master of Trinity College Cambridge, a position he held until his 1990 age mandated retirement. Sir Andrew lived out his days in Cambridgeshire and continued teaching at Trinity College until his death.

Treatment of infection in burns
Burn injury damages the skin which is the primary barrier to infection. Damaged skin that provides a fertile ground to bacterial growth, together with immunosuppression that accompanies major burns, are the main contributors to wound infection, invasive sepsis and if not managed, death. With the advancement of resuscitation methods in burn patients, deaths due to hypovolemia and hyperosmolar shock are now uncommon. Meanwhile, sepsis is now the commonest cause of death following burn injury and contributes to almost 75–85% of all burn victim deaths.[8,9] Over the last few decades, many advancements have positively impacted on the incidence of burn wound infections and these include, topical and systemic antimicrobial therapies, early burn wound excision and closure and the introduction of infection control measures in modern burn units such as isolation facilities.
The discovery of penicillin by the Scottish scientist, Sir Alexander Fleming in 1928 was a major breakthrough in the fight against microbial infections but it was not until World War II (WW2) that a way to manufacture the drug in large industrial scale was achieved. Penicillin played a crucial part in the treatment of the burn victims of the Coconut Grove fire in Boston in 1942, as it combated the Staphylococcus bacteria which typically led to toxic shock syndrome and also infected skin grafts. The emergence of methicillin-resistant staphylococcal strains however curbed the effectiveness of natural penicillins as the penicillinase produced by these bacteria hydrolyse the penicillin B-lactam ring and render them ineffective which in turn necessitated the development of penicillinase-resistant penicillins such as methicillin and cloxacillin. Streptococcal organisms are a major bane in the treatment of burn injuries as even the presence of a few B-hemolytic streptococci such as Group A (Streptococcus pyogenes) and Group B (Streptococcus agalactiae) can lead to a wound infection, loss of skin grafts and failure of a primary wound closure. Fortunately, natural penicillins remain effective and are bactericidal to these bacteria. Although staphyloccocal and streptococcal infections remain a major problem in burns, the landscape of microbes in burns continues to evolve with the emergence of antibiotic resistant strains e.g. the vancomycin-resistant enterococci (VRE) and Pseudomonas spp. which is now one of the most repeatedly encountered wound pathogen and a leading cause of noscomial infections in burn patients.
The aim of topical therapies has changed over the centuries as we understand increasingly more about the pathophysiology of burn wounds. In the early 20 th century, the goal of topical therapies was to prevent the release of ‘toxins’ from the burn wound and to dry out the wound to allow formation of a hard coagulum to minimize fluid loss. A variety of therapies were developed to achieve this such as the tannic acid spray described by Davidson in 1925 which was believed to produce a cleaner wound. However its use was stopped when it was found to be a hepatotoxic.
One of the first topical antimicrobial treatments discovered was sodium hypochlorite (NaClO) in the 18 th century by Berthollet. Its use was hampered by irritation it caused, but this was later discovered to be due to its variable quality and the free alkali or chlorine it contained. In 1915, Dr. Henry Dakin successfully developed a method of synthesizing hypochlorite without its irritating contaminants and found initially that a concentration of 0.5% was most effective as an antiseptic solution (revised later to 0.025%). This was further developed and used successfully in the treatment of burn wounds with a protocol of mechanical cleansing, surgical debridement and topical application of hypochlorite solution.
The major milestone in topical burn therapy was the application of solutions of silver compounds or salts, which played an important role in reducing the rate of burn wound sepsis and mortality. Silver sulfadiazine was developed by Charles Fox in the 1960’s and has become the mainstay of topical antimicrobial therapy due to its success in controlling infection and minimal side effect profile. Mafenide acetate (Sulfamylon) briefly was a viable alternative to the use of silver compound solutions in the treatment of infections but due to its carbonic anhydrase inhibitory effects which can lead to systemic acidosis, its use was all but discontinued except in cases of treatment of invasive wound infections. The other common silver-based therapy was silver nitrate, described by Moyer et al. in 1965. Silver based topical treatments were successful in controlling infections especially Pseudomonas aeroginosa infections.
Recent development in dressing technology have seen the use of a variety of interesting materials incorporated into the dressing. There is emerging evidence for the use of dressings and gels[18–21] containing the naturally occurring glycosaminoglycan, chitin, which prevents early extension of burn injury, has antimicrobial properties,[23,24] promotes fibroblast proliferation and angiogenesis and may promote burn wounds to heal, effects that are augmented by the incorporation of growth factors into the gel.[26,27] There has also been studies on the use of carbon fibre in dressings which has been shown to increase the absorptive capacity of the dressing, reduce inflammation, reduce bacterial growth and promote healing.[28,29]
Role of non-pharmalogical therapies
Although antibiotic treatment is a major front in the war against infection, non-pharmalogical interventions play equally important roles, such as strict handwashing and hygenic nursing standards and patient isolation. The need for strict burn patient isolation became an important issue after WW2. State of the art burn centres were established in the United States then across the world. The Brooks Army center is an example of facility that was designed with infection control and patient isolation in mind.
Cell types used in skin regeneration
Cells are the main component of the tissue-engineered skin used for burn therapies (Table 1). They include both stem and somatic cells and can be divided into three main groups: autologous, allogeneic, and xenogeneic. One of the main trends in choosing a cell type for patient treatment is the use of autologous cells as they do not cause immune rejection and their tumorigenicity is low due to the absence of epigenetic manipulations. Nowadays, animal cells are not widely used for skin tissue regeneration, only ECM or its components that they synthesize. Plant stem cells, which are commonly applied in cosmetics, can be interesting as they have no use limitations when compared to animal and human cells. Of course, they cannot be used in skin substitute development as a cell component but they can provide bioactive substances, which can improve the wound healing process .
Fibroblasts and keratinocytes are common cells used in products for wound and burn healing . Keratinocytes are the major cell component of the epidermis and responsible for its stratified structure and form numerous tight intercellular junctions. Fibroblasts are the main cell type of the dermis and produce ECM components and secrete various growth factors (TGF-β), cytokines (TNF-α), and matrix metalloproteinases, which ensure the ECM formation and keratinocyte proliferation and differentiation . Commercial products such as Epicel, Cryoskin, and BioSeed-S contain keratinocytes Dermagraft, TransCyte and Hyalograft 3D—fibroblasts and Apligraf, Theraskin, and OrCell—a combination. The use of these cells enables the large-scale production of standardized product batches. However, these materials are mostly non-permanent bioactive dressings, which provide cytokines, ECM, and growth factors for the successful skin reparation [41,42,43]. Immune rejection is commonly reported with allogeneic fibroblasts and keratinocytes,  but this is mostly shown for allogeneic keratinocytes that can be explained by the difference in HLA expression and cytokine production . Fetal fibroblasts are of particular interest because they can significantly improve skin repair due to the high expansion ability, low immunogenicity, and intense secretion of bioactive substances such as basic fibroblast growth factor, vascular endothelial growth factor, and keratinocyte growth factor. However, ethical issues limit their application [46,47,48,49].
Epidermal stem cells (ESC) are of particular interest for skin tissue regeneration as they have favorable features such as high proliferation rate and easy access and keep their potency and differentiation potential for long periods [65, 82]. They are one of the skin stem cell types, either heterogeneous or autogenous origins (Table 2). ESC are mostly connected to the process of skin regeneration . They are rare, infrequently divide and generate short-lived and rapidly dividing cells, which are involved in the regeneration process . Their main population, responsible for skin repair, is located in the basal layer of the epidermis however, they can also be revealed in the base of sebaceous glands and the bulge region of hair follicles [6, 65, 82]. However, while working with ESC culture, we may face progressive aneuploidy or polyploidy and mutation accumulation after several passages. Moreover, as they can be easily derived from the patient’s skin and transplanted to the same patient, ESC are not restricted by ethical issues. Grafts containing autologous holoclones ESC have proven to be effective in treating vast skin defects: epidermolysis, skin and ocular burns, etc. [83, 84].
Mesenchymal stromal cells (MSC) have similar (not identical) features as ESC and can be derived from various tissues, even the skin as mentioned previously . They have a high differentiation potential and a certain degree of plasticity and may generate cells of mesodermal, ectodermal, and endodermal lineages . Moreover, paracrine, trophic, and immunomodulatory MSC properties enable their clinical use [100, 101]. MSC can migrate to the injured tissues, differentiate, and regulate the tissue regeneration by the production of growth factors, cytokines, and chemokines . Their immunomodulatory activity is based on the release of anti-inflammatory cytokines and the inhibition of proliferation of CD4 + and CD8 + natural killer cells, T cells, and B cells. MSC are considered to be hypoimmunogenic because they do not express class I and II molecules of the major histocompatibility complex (MHC) and co-stimulatory proteins (e.g., CD40, CD80, CD86). Therefore, the transplantation of allogenic MSC has a low risk of the immune rejection [103,104,105]. In burn therapy, adipose-derived stromal cells refined from the stromal vascular fraction are widely applied because of their easy access and isolation procedure and inspiring improvement of the healing processes [106,107,108]. They are showed to preserve their therapeutic effects after freezing that ensures their multiple use . It is worth mentioning that even the freshly isolated stromal vascular fraction is showed to be effective in burn therapy , but compared to adipose-derived stromal cells, it can release high concentrations of inflammatory mediators . However, the number of randomized controlled preclinical and clinical trials remains insufficient .
Among the MSC derived from other tissues (adipose tissue, umbilical cord, etc.) the MSC derived from bone marrow (BMSC) requires special attention. They also possess plasticity and can differentiate into tissues of mesodermal, ectodermal, and endodermal origin [112, 113]. BMSC are considered to participate in the skin development. It has been reported that bone marrow can generate not only hematopoietic and mesenchymal cells but also fibroblast-like cells that are located in the dermis and actively proliferate in the skin during the regeneration processes [69, 114, 115]. The possible disadvantages of BMSC are that the tumor microenvironment may induce changes in the angiogenesis ability and anti-tumor response. Moreover, they may generate tumor-associated fibroblasts and shift a normal immune cell phenotype to an immunosuppressive and tumor promoting one .
However, nowadays, the greatest interest in tissue regeneration belongs to induced pluripotent stem cells (iPSC) using somatic cell reprogramming like a magic wand, we can develop patient-specific cells with a tailored phenotype and apply them in clinics . The most commonly used cells for cell reprogramming are dermal fibroblasts, melanocytes, and keratinocytes since they can be easily accessed and isolated from punch biopsies . Research has shown that both murine and human iPSC can be differentiated into dermal fibroblasts , keratinocytes , and melanocytes , opening a door for iPSC technology into dermatology applications. The interesting fact is that fibroblasts achieved via this technique may show increased properties compared to those of the parental fibroblasts, e.g., the exceeded ECM production . This might be related to the changed epigenetic signature that occurs during iPSC differentiation and is critical for their use in skin tissue regeneration. However, when cells are reprogrammed with tumorigenic c-Myc and this transgene remains in iPSC, the risk of tumor formation increases, because c-Myc might be reactivated . Since modern methods for cell purification cannot ensure the full separation of differentiated cells from iPSC, undifferentiated and partly differentiated cells may be implanted into a patient and increase the possibility of tumor formation .
In third-degree burn treatment, hydrogel helps grow new, scar-free skin
Johns Hopkins researchers have developed a jelly-like material and wound treatment method that, in early experiments on skin damaged by severe burns, appeared to regenerate healthy, scar-free tissue.
In the Dec. 12-16 online Early Edition of Proceedings of the National Academy of Sciences, the researchers reported their promising results from mouse tissue tests. The new treatment has not yet been tested on human patients. But the researchers say the procedure, which promotes the formation of new blood vessels and skin, including hair follicles, could lead to greatly improved healing for injured soldiers, home fire victims and other people with third-degree burns.
Dextran hydrogel for burn wound healing. (A) Surgery procedure: We placed wounds on the posterior-dorsum of each mouse and performed burn wound excisions after 48 h. We covered wounds with either dextran hydrogels or control scaffold, followed by their coverage with dressing. We covered the control wounds only with dressing. (B) Photo image of wound healing within 21 d demonstrate a more complete wound healing in burn wounds treated with dextran hydrogel than in wounds treated with control scaffolds or dressing alone.
The treatment involved a simple wound dressing that included a specially designed hydrogel—a water-based, three-dimensional framework of polymers. This material was developed by researchers at Johns Hopkins’ Whiting School of Engineering, working with clinicians at the Johns Hopkins Bayview Medical Center Burn Center and the Department of Pathology at the university’s School of Medicine.
Third-degree burns typically destroy the top layers of skin down to the muscle. They require complex medical care and leave behind ugly scarring. But in the journal article, the Johns Hopkins team reported that their hydrogel method yielded better results. “This treatment promoted the development of new blood vessels and the regeneration of complex layers of skin, including hair follicles and the glands that produce skin oil,” said Sharon Gerecht, an assistant professor of chemical and biomolecular engineering who was principal investigator on the study.

Gerecht said the hydrogel could form the basis of an inexpensive burn wound treatment that works better than currently available clinical therapies, adding that it would be easy to manufacture on a large scale. Gerecht suggested that because the hydrogel contains no drugs or biological components to make it work, the Food and Drug Administration would most likely classify it as a device. Further animal testing is planned before trials on human patients begin. But Gerecht said, “It could be approved for clinical use after just a few years of testing.”
John Harmon, a professor of surgery at the Johns Hopkins School of Medicine and director of surgical research at Bayview, described the mouse study results as “absolutely remarkable. We got complete skin regeneration, which never happens in typical burn wound treatment.”
If the treatment succeeds in human patients, it could address a serious form of injury. Harmon, a coauthor of the PNAS journal article, pointed out that 100,000 third-degree burns are treated in U. S. burn centers like Bayview every year. A burn wound dressing using the new hydrogel could have enormous potential for use in applications beyond common burns, including treatment of diabetic patients with foot ulcers, Harmon said.
Guoming Sun, Gerecht’s Maryland Stem Cell Research Postdoctoral Fellow and lead author on the paper, has been working with these hydrogels for the last three years, developing ways to improve the growth of blood vessels, a process called angiogenesis. “Our goal was to induce the growth of functional new blood vessels within the hydrogel to treat wounds and ischemic disease, which reduces blood flow to organs like the heart,” Sun said. “These tests on burn injuries just proved its potential.”
Gerecht says the hydrogel is constructed in such a way that it allows tissue regeneration and blood vessel formation to occur very quickly. “Inflammatory cells are able to easily penetrate and degrade the hydrogel, enabling blood vessels to fill in and support wound healing and the growth of new tissue,” she said. For burns, the faster this process occurs, Gerecht added, the less there is a chance for scarring.
Originally, her team intended to load the gel with stem cells and infuse it with growth factors to trigger and direct the tissue development. Instead, they tested the gel alone. “We were surprised to see such complete regeneration in the absence of any added biological signals,” Gerecht said.
Sun added, “Complete skin regeneration is desired for various wound injuries. With further fine-tuning of these kinds of biomaterial frameworks, we may restore normal skin structures for other injuries such as skin ulcers.”
Gerecht and Harmon say they don’t fully understand how the hydrogel dressing is working. After it is applied, the tissue progresses through the various stages of wound repair, Gerecht said. After 21 days, the gel has been harmlessly absorbed, and the tissue continues to return to the appearance of normal skin.
The hydrogel is mainly made of water with dissolved dextran—a polysaccharide (sugar molecule chains). “It also could be that the physical structure of the hydrogel guides the repair,” Gerecht said. Harmon speculates that the hydrogel may recruit circulating bone marrow stem cells in the bloodstream. Stem cells are special cells that can grow into practically any sort of tissue if provided with the right chemical cue. “It’s possible the gel is somehow signaling the stem cells to become new skin and blood vessels,” Harmon said.
Neovascularization is a critical determinant of wound-healing outcomes for deep burn injuries. We hypothesize that dextran-based hydrogels can serve as instructive scaffolds to promote neovascularization and skin regeneration in third-degree burn wounds. Dextran hydrogels are soft and pliable, offering opportunities to improve the management of burn wound treatment. We first developed a procedure to treat burn wounds on mice with dextran hydrogels. In this procedure, we followed clinical practice of wound excision to remove full-thickness burned skin, and then covered the wound with the dextran hydrogel and a dressing layer. Our procedure allows the hydrogel to remain intact and securely in place during the entire healing period, thus offering opportunities to simplify the management of burn wound treatment. A 3-week comparative study indicated that dextran hydrogel promoted dermal regeneration with complete skin appendages. The hydrogel scaffold facilitated early inflammatory cell infiltration that led to its rapid degradation, promoting the infiltration of angiogenic cells into the healing wounds. Endothelial cells homed into the hydrogel scaffolds to enable neovascularization by day 7, resulting in an increased blood flow significantly greater than treated and untreated controls. By day 21, burn wounds treated with hydrogel developed a mature epithelial structure with hair follicles and sebaceous glands. After 5 weeks of treatment, the hydrogel scaffolds promoted new hair growth and epidermal morphology and thickness similar to normal mouse skin. Collectively, our evidence shows that customized dextran-based hydrogel alone, with no additional growth factors, cytokines, or cells, promoted remarkable neovascularization and skin regeneration and may lead to novel treatments for dermal wounds.

Granulocyte/macrophage colony-stimulating factor treatment of human chronic ulcers promotes angiogenesis associated with de novo vascular endothelial growth factor transcription in the ulcer bed
Background Granulocyte/macrophage colony-stimulating factor (GM-CSF), a cytokine with pleiotropic functions, has been successfully employed in the treatment of chronic skin ulcers. The biological effects underlying GM-CSF action in impaired wound healing have been only partly clarified.
Objectives To investigate the effects of GM-CSF treatment of chronic venous ulcers on lesion vascularization and on the local synthesis of the angiogenic factors vascular endothelial growth factor (VEGF) and placenta growth factor (PlGF).
Methods Patients with nonhealing venous leg ulcers were treated with intradermal injection of recombinant human GM-CSF, and biopsies were taken at the ulcer margin before and 5 days after administration. Wound vascularization was analysed by immunohistochemistry using antiplatelet endothelial cell adhesion molecule-1/CD31 and anti-α-smooth muscle actin antibodies. VEGF and PlGF transcription was assessed by in situ hybridization. To identify the cell populations transcribing VEGF within the ulcer bed, the VEGF hybridization signal was correlated with the immunostaining for different cell type markers on serial sections. Direct induction of VEGF transcription by GM-CSF was investigated in GM-CSF-treated cultured macrophages and keratinocytes.
Results Blood vessel density was significantly increased in the ulcer bed following GM-CSF treatment. VEGF transcripts were localized in keratinocytes at the ulcer margin both before and after GM-CSF treatment, whereas a VEGF hybridization signal was evident within the ulcer bed only following administration. PlGF mRNA was barely detectable in keratinocytes at the ulcer margin and was not visibly increased after treatment. Unlike VEGF, a specific PlGF hybridization signal could not be detected in cells within the ulcer following GM-CSF administration. Monocytes/macrophages were the main cell population transcribing VEGF after GM-CSF treatment. In vitro analysis demonstrated that VEGF transcription can be directly stimulated by GM-CSF in a differentiated monocytic cell line, but not in keratinocytes.
Conclusions Our data show that increased vascularization is associated with GM-CSF treatment of chronic venous ulcers and indicate that inflammatory cell-derived VEGF may act as an angiogenic mediator of the healing effect of GM-CSF in chronic ulcers.

Genetically Engineered Skin to Treat Disease, Promote Scarless Wound Healing, and More
Xiaoyang Wu is using genetically modified skin as an engineering platform to provide a solution for diseases beyond skin disorders.
The largest organ in the human body, skin is a robust system with great potential to support not only basic research, but to serve as a platform for stem cell engineering.
This is the focus of Xiaoyang Wu’s work, which is dedicated to understanding the dynamics, signaling, and clinical applications of skin stem cells. Wu has been working in the field for more than 30 years and is currently an associate professor in the Ben May Department of Cancer Research at the University of Chicago. He also is the founder of two companies, GeCell Therapeutics and Maponos Therapeutics.
With the help of the Polsky for Entrepreneurship and Innovation, Wu has patented an engineering platform for healing and treating skin disease by using genetically modified skin.
Beyond skin disease, however, Wu has developed skin grafts that can deliver specific proteins, detect compounds, and remove harmful toxins from the body, to treat various diseases. This includes rare genetic disorders, hemophilia, obesity, and diabetes.
Among other uses, Wu in 2018 described a novel approach to quell cocaine addiction and protect against overdose. The studies, conducted in mice, involved adding the anti-cocaine gene to the animal’s skin’s cells, which were then grafted back onto the mouse.
According to the researchers, “Cutaneous gene therapy through skin transplants that elicit drug elimination may offer a therapeutic option to address drug abuse.”
Scarless Wound Healing
Combining skin biology with material synthesis, Wu also has filed a patent for a new material that will be able to help skin wounds heal without scarring.
“For severe skin wounds, scarring is the most significant post-treatment issue for the patient,” explained Wu, who is developing a way to eliminate scars by manipulating the pathways of healing. The process is tricky, he said, because these pathways are also important to heal wounds.
“We have to find a better way to control the pathway,” Wu explained, noting that they are working to design a particle that would only block this pathway after a certain time point, because in the early phase of healing, this pathway needs to be unencumbered.
“During the resolution phase in skin wound healing, we need to suppress that signal,” said Wu, “Because too much will promote fibrosis in the dermal tissue leading to scarring.”
In collaboration with other researchers at the University of Houston, Wu also is exploring the use of Drawn-on-Skin (DoS) electronics for sensing and point-of-care treatment. These electronics are created by drawing on human skin with liquid semiconducting inks.
“Human skin offers a wealth of physiological and physical information that can be utilized to monitor, prevent, and treat adverse health conditions. Through directly interfacing electronic devices with the skin, information such as the state of the heart, the condition of muscle, the impedance, and hydration of the skin, can all be extracted,” the researchers explained in a paper published in Nature Communications earlier this year.
For this work, Wu’s lab tested the writable ink on skin grafts grown in his lab where he tested for any adverse reactions. “By providing electrical stimulation we can enhance wound healing,” said Wu, speaking to the use of DoS electronics. The researchers also are exploring other ways of using the ink.
As Wu explained, the goal is to change the skin into a sort of sensing device that could detect abnormal activity, such as those leading up to a heart attack or stroke. Using an engineered skin graft, the writeable ink could be used to translate changes into a signal that is viewable.
“Patients could use a phone or another device to get a warning about something critical ongoing in their body,” Wu said.
Wu is among several University of Chicago researchers showcasing their work at Illinois Ignite 2020. Pre-recorded presentations will be posted on September 24, 2020, and will remain live until October 9, 2020.
