Topical Collection Information

Dear Colleagues,

The ability to heal wounds has always given a decisive evolutionary advantage to species, and especially to human beings. Therefore, it represents one of the most important biological processes in the human organism. Although the experimental research, especially in the last few decades, has presented the general steps in the wound-healing process and some significant progress in the treatment of wounds has been achieved, many questions remain unanswered. In addition, chronic or non-healing wounds represent a growing health problem worldwide. The underlying pathogenesis of chronic wounds is further complicated by factors such as advanced age, poor nutrition, metabolic disorders, and immunosuppression, which trigger additional cellular and systemic stress and thus delay the wound-healing process.

This Topical Collection will provide up-to-date information regarding the general steps in the wound-healing process with its participant cells, the extracellular matrix, cytokines, chemokines, and growth factors, as well as their interactions with the microenvironment during various phases. Furthermore, differences in wound-healing processes in different skin tissues such as mucosa, scar, genital skin, and in pathologic skin wound-healing processes are discussed. A further focus will be on current conservative and surgical measures that can be taken to improve wound healing and modern wound management.

Therefore, we look forward to receiving a comprehensive overview of this topic which highlights the current knowledge and therapies in skin wound healing and provides future outlooks regarding interesting and promising approaches to address the current problems in wound-healing disorders.

The combination of adipose-derived stem cells (ASCs) and dermal scaffolds has been shown to be an approach with high potential in soft tissue reconstruction. The addition of dermal templates to skin grafts can increase graft survival through angiogenesis, improve regeneration and healing time, and enhance the overall appearance. However, it remains unknown whether the addition of nanofat-containing ASCs to this construct could effectively facilitate the creation of a multi-layer biological regenerative graft, which could possibly be used for soft tissue reconstruction in the future in a single operation. Initially, microfat was harvested using Coleman’s technique, then isolated through the strict protocol using Tonnard’s technique. Finally, centrifugation, emulsification, and filtration were conducted to seed the filtered nanofat-containing ASCs onto Matriderm for sterile ex vivo cellular enrichment. After seeding, a resazurin-based reagent was added, and the construct was visualized using two-photon microscopy. Within 1 h of incubation, viable ASCs were detected and attached to the top layer of the scaffold. This experimental ex vivo note opens more dimensions and horizons towards the combination of ASCs and collagen–elastin matrices (i.e., dermal scaffolds) as an effective approach in soft tissue regeneration. The proposed multi-layered structure containing nanofat and dermal template (Lipoderm) may be used, in the future, as a biological regenerative graft for wound defect reconstruction and regeneration in a single operation and can also be combined with skin grafts. Such protocols may optimize the skin graft results by creating a multi-layer soft tissue reconstruction template, leading to more optimal regeneration and aesthetic outcomes. Full article

Background: Increased lifespan and the improvement of medical treatment have given rise to research in reconstructive procedures in elderly patients. Higher postoperative complication rates, longer rehabilitation, and surgical difficulties remain a problem in the elderly. We asked whether a free flap in elderly patients is an indication or a contraindication and performed a retrospective, monocentric study. Methods: Patients were divided into two groups (YOUNG 0–59 years; OLD > 60 years). The endpoint was the survival of flaps and their dependence on patient- and surgery-specific parameters using multivariate analysis. Results: A total of 110 patients (OLD n = 59) underwent 129 flaps. The chance of flap loss increased as soon as two flaps were performed in one surgery. Anterior lateral thigh flaps had the highest chance for flap survival. Compared with the lower extremity, the head/neck/trunk group had a significantly increased chance of flap loss. There was a significant increase in the odds of flap loss in linear relation to the administration of erythrocyte concentrates. Conclusion: The results confirm that free flap surgery can be indicated as a safe method for the elderly. Perioperative parameters such as two flaps in one surgery and transfusion regimens must be considered as risk factors for flap loss. Full article

Electrical stimulation of the cell can have a number of different effects depending on the type of cell being stimulated. In general, electrical stimulation can cause the cell to become more active, increase its metabolism, and change its gene expression. For example, if the electrical stimulation is of low intensity and short duration, it may simply cause the cell to depolarize. However, if the electrical stimulation is of high intensity or long duration, it may cause the cell to become hyperpolarized. The electrical stimulation of cells is a process by which an electrical current is applied to cells in order to change their function or behavior. This process can be used to treat various medical conditions and has been shown to be effective in a number of studies. In this perspective, the effects of electrical stimulation on the cell are summarized. Full article
