Abstract
Importance It is necessary to determine whether safety and efficacy of autologous skin tissue cells grafting for facial sunken or flat scars. Objective To identify autologous skin tissue cells grafting can reduce facial sunken or flat scars. Design setting and participants In this retrospective cross-sectional study, a total of 128 patients with scar (exclude pathological scar patients), who were receiving autologous skin tissue cells grafting therapy from January 1, 2016, to December 31, 2019. Interventions Autologous skin tissue cells grafting. Main outcomes and measures Changes in scar severity, color changes in the scar area, infection rate and patient satisfaction. Results A total of 128 patients with scar (89 females [69.5%]; mean [SD] age, 30.6 [13.12] years) received autologous skin tissue cells grafting therapy. SCAR (Scar Cosmesis Assessment and Rating), with scores ranging from 0 (best possible scar) to 15 (worst possible scar). After treatment 12 months, the mean [SD] of SCAR score went down from 9.85 [1.33] to 2.67 [1.21]. No infection was observed during treatment or recovery, and the main drawback after autologous skin tissue cells grafting is that the color recovery time is longer. The patient satisfaction 6 months after treatment was 85.2%, furthermore 12 months after treatment patient satisfaction was 94.7%. Conclusions and relevance In this study, autologous skin tissue cells grafting was safe and effective to treat facial scars. Therefore, autologous skin tissue cells grafting may be recommended as a reliable treatment for facial scar.

Abstract
Electrospun nanofibers show great potential in biomedical applications. This mini review article traces the recent advances in electrospun nanofibers for wound management via various approaches. Initially, we provide a short note on the four phases of wound healing, including hemostasis, inflammation, proliferation, and remodeling. Then, we state how the nanofiber dressings can stop bleeding and reduce the pain. Following that, we discuss the delivery of therapeutics and cells using different types of nanofibers for enhancing cell migration, angiogenesis, and re-epithelialization, resulting in the promotion of wound healing. Finally, we present the conclusions and future perspectives regarding the use of electrospun nanofibers for wound management.

Abstract
Background The morbidity of the donor site in split-thickness skin graft (STSG) may include abnormal pigmentation, delayed healing, and unfavorable scarring. Studies are usually focused on improving the healing of the recipient site, so donor site management becomes a secondary consideration. An optimal solution should be sought for donor site management to improve healing and minimize morbidity. Methods In this study, we used minced residual skin grafts over half of the donor site (cases) and compared the healing duration and scar quality with the other half (control). Healing duration was measured in days and the scar quality was assessed by the Patient and Observer Scar Assessment Scale (POSAS) at 90 days, 180 days, and 360 days. Results The healing time was reduced with the application of minced residual skin grafts on the donor site. The scar quality was significantly better in the case group as compared to the control group at 90 days, 180 days, and 360 days (p<0.05). Conclusion Mincing residual skin grafts and replacing them back to the donor site reduces the healing time and improves the quality of the scar.

Abstract
Wound healing is a complex process in tissue regeneration through which the body responds to the dissipated cells as a result of any kind of severe injury. Diabetic and non-healing wounds are considered an unmet clinical need. Currently, different strategic approaches are widely used in the treatment of acute and chronic wounds which include, but are not limited to, tissue transplantation, cell therapy and wound dressings, and the use of an instrument. A large number of literatures have been published on this topic; however, the most effective clinical treatment remains a challenge. The wound dressing involves the use of a scaffold, usually using biomaterials for the delivery of medication, autologous stem cells, or growth factors from the blood. Antibacterial and anti-inflammatory drugs are also used to stop the infection as well as accelerate wound healing. With an increase in the ageing population leading to diabetes and associated cutaneous wounds, there is a great need to improve the current treatment strategies. This research critically reviews the current advancement in the therapeutic and clinical approaches for wound healing and tissue regeneration. The results of recent clinical trials suggest that the use of modern dressings and skin substitutes is the easiest, most accessible, and most cost-effective way to treat chronic wounds with advances in materials science such as graphene as 3D scaffold and biomolecules hold significant promise. The annual market value for successful wound treatment exceeds over $50 billion US dollars, and this will encourage industries as well as academics to investigate the application of emerging smart materials for modern dressings and skin substitutes for wound therapy.

Evolution of a concept with enzymatic debridement and autologous in situ cell and platelet-rich fibrin therapy (BroKerF). Scars Burn Heal 2022; 8:20595131211052394.

Abstract
BACKGROUND Deep partial-thickness burns are traditionally treated by tangential excision and split thickness skin graft (STSG) coverage. STSGs create donor site morbidity and increase the wound surface in burn patients. Herein, we present a novel concept consisting of enzymatic debridement of deep partial-thickness burns followed by co-delivery of autologous keratinocyte suspension and plated-rich fibrin (PRF) or fibrin glue. MATERIAL AND METHODS In a retrospective case study, patients with deep partial-thickness burns treated with enzymatic debridement and autologous cell therapy combined with PRF or fibrin glue (BroKerF) between 2017 and 2018 were analysed. BroKerF was applied to up to 15% total body surface area (TBSA); larger injuries were combined with surgical excision and skin grafting. Exclusion criteria were age <18 or >70 years, I°, IIa°-only, III° burns and loss of follow-up. RESULTS A total of 20 patients with burn injuries of 16.8% ± 10.3% TBSA and mean Abbreviated Burn Severity Score 5.45 ± 1.8 were identified. Of the patients, 65% (n = 13) were treated with PRF, while 35% (n = 7) were treated with fibrin glue. The mean area treated with BroKerF was 7.5% ± 0.05% TBSA, mean time to full epithelialization was 21.06 ± 9.2 days and mean hospitalization time was 24.7 ± 14.4 days. Of the patients, 35% (n = 7) needed additional STSG, 43% (n = 3) of whom had biopsy-proven wound infections. CONCLUSION BroKerF is an innovative treatment strategy, which, in our opinion, will show its efficacy when higher standardization is achieved. The combination of selective debridement and autologous skin cells in a fibrin matrix combines regenerative measures for burn treatment. LAY SUMMARY Patients suffering from large burn wounds often require the use of large skin grafts to bring burned areas to heal. Before the application of skin grafts, the burned skin must be removed either by surgery or using enzymatic agents. In this article, we describe a method where small areas of skin are taken and skin cells are extracted and sprayed on wound areas that were treated with an enzymatic agent. The cells are held in place by a substance extracted from patients' blood (PRF) that is sprayed on the wound together with the skin cells. We believe this technique can be helpful to reduce the need of skin grafts in burned patients and improve the healing process.

Abstract
Autologous skin grafting was developed more than 3500 years ago. Several approaches and techniques have been discovered and established in burn care since then. Great achievements were made during the 19th and 20th century. Many of these techniques are still part of the surgical burn care. Today, autologous skin grafting is still considered to be the gold standard for burn wound coverage. The present paper gives an overview about the evolution of skin grafting and its usage in burn care nowadays.

Abstract
The purpose of this systematic literature review is to critically evaluate split-thickness skin graft (STSG) donor-site morbidities. The search of peer-reviewed articles in three databases from January 2009 to July 2019 identified 4271 English-language publications reporting STSG donor-site clinical outcomes, complications, or quality of life. Of these studies, 77 met inclusion criteria for analysis. Mean time to donor-site epithelialization ranged from 4.7 to 35.0 days. Mean pain scores (0-10 scale) ranged from 1.24 to 6.38 on postoperative Day 3. Mean scar scores (0-13 scale) ranged from 0 to 10.9 at Year 1. One study reported 28% of patients had donor-site scar hypertrophy at 8 years. Infection rates were generally low but ranged from 0 to 56%. Less frequently reported outcomes included pruritus, wound exudation, and esthetic dissatisfaction. Donor-site wounds underwent days of wound care and were frequently associated with pain and scarring. Widespread variations were noted in STSG donor-site outcomes likely due to inconsistencies in the definition of outcomes and utilization of various assessment tools. Understanding the true burden of donor sites may drive innovative treatments that would reduce the use of STSGs and address the associated morbidities.

Abstract
ABSTRACT Pyoderma gangrenosum (PG) is a rare neutrophilic dermatosis that usually presents as a painful ulcer with erythematous and undermined borders and is often characterized by pathergy. Although this condition precludes a surgical approach, in cases resistant to treatment with immunosuppressive agents, skin grafts and amputation are considered last resorts. Both expose the patient to the risk of developing new lesions. A minimally invasive autologous graft, "minced micrografts," is a possible alternative to speed up the healing process, reducing the risk of pathergy.This procedure was implemented in a 28-year-old man with PG who was prescribed prednisone and dapsone and who had a large ulcer on the arm and armpit that had persisted for 4 months and was undergoing slow re-epithelialization. A sample of finely minced skin previously taken from the clavicular region suspended in a hydrogel was spread on the wound bed in a proportion of less than 1:6 with respect to the receiving site. Seven days later, initial signs of re-epithelialization appeared, and the wound healed in 3 months.In patients with PG, the minced micrograft method could facilitate ulcer healing by releasing cytokines, chemokines, and growth factors, thus promoting granulation tissue formation, neoangiogenesis. Because this method does not require special equipment or complex surgical techniques and is very low cost, it should be an integral part of the arsenal of procedures aimed at improving the quality of life of patients with PG.
