New human skin being made from fish skin

A total of ten studies were selected that investigated the efficacy of fish skin grafts by either comparing them to another wound healing technique or by observing wound healing with fish skin grafts and recording the outcomes. AFS showed better healing compared with collagen alginate dressing, silver sulfadiazine cream 1%, and allograft. Although there is no single specific gold standard technique for wound healing, fish skin grafts demonstrated overall better and faster wound healing, fewer dressing changes, less pain, and lower cost. acellular fish skin; burn wounds; Dehydrated human amnion/chorion membrane transplants, fish skin transplants, leg ulcers, xenografts. Fish skin grafts are used for wound healing. Fish skin grafts have anti-inflammatory properties and help in wound healing.

Fish skin graft, a new skin substitute,
FDA has seen widespread clinical application since its approval for wound coverage. Due to its properties in promoting wound healing and its efficient cost in manufacturing, fish skin grafts are a potential alternative to allograft and xenograft sources in various applications, including, but not limited to, cadaver and porcine grafts. Additionally, fish skin grafts can help in healing diabetic foot ulcers (
DFUs), venous leg ulcers (
VLUs) and there is some evidence worthy of further exploration in the treatment of several other acute and chronic wounds. Here we summarize the materials and biological properties of fish skin grafts. How this graft compares to other popular skin substitutes on the market for different types of wounds was also explored. Fish skin grafts have many uses in future clinical applications.

As the largest organ in the human body, skin has a complex structure. It plays an important role as the first line of defense that acts as a barrier to the external environment, making it susceptible and vulnerable. When the structural integrity of skin tissue is disrupted (torn, cut, or punctured), pathogenic organisms and foreign bodies can easily enter and contaminate the wound. If a healthy person's wound site is not infected, the skin may heal without any additional treatment. However, if the site becomes infected with microorganisms, the healing process will easily become stuck in the inflammatory phase or biofilms may develop that will delay dermal and subcutaneous wound healing. There are certain circumstances when a wound may remain inflamed and become chronic even if it is not caused by pathogenic infection, including disorders such as diabetes, hypersensitivity reactions to materials used to treat the wound, overexpression of M1 macrophages. Phenotypic changes include, but are not limited to, overexpression, dysregulated matrix metalloproteinases, and fibroblast and keratinocyte senescence. Left untreated, chronic wounds can develop and lead to fatal complications. Regenerative medicine aims to focus on growing and replacing damaged tissues and organs, resulting in long-lasting, permanent solutions. The main strategy is to promote the growth and proliferation of host cells at the injury site and allow faster healing time. The body's innate healing and repair mechanisms can be influenced to promote regeneration. Skin grafts provide a promising and effective solution for regenerative medicine in the skin. By acting as a temporary barrier as well as providing antimicrobial properties, skin grafts show the ability to promote healing more effectively than traditional wound dressings.

A variety of non-allogeneic – non-cellular tissue-based therapies exist, which exhibit key characteristics that promote wound healing. However, none has achieved all the characteristics of an ideal skin-replacement material. Since new wounds have to be created to collect skin grafts from donor sites in the case of autografts, surgical morbidity is a cause for concern. Full-thickness cellular and/or tissue-based products (CTP) using allografts are a prevalent dermatological repair option. However, except in autografts, due to the large diversity of antibodies and antigens present within the CTP, graft rejection is another factor leading to adverse conditions for the CTP recipient. In one case study, a patient showed chronic antibody-mediated allograft rejection 25 years after implantation. Although allograft is commonly used in dermatology, it is not the ideal form of skin graft. Some of the highly valued features of skin replacement material are cost effectiveness, availability, long term function, conformability to irregular wound, deep wound application, low immunological response and high biologic acellular fish skin graft is in demand as a potential candidate to fill this gap. Work as.

Acellular fish skin is obtained from Atlantic cod. Compared to mammalian source skin cellular or tissue based product treatments (CTP), they have a much lower risk of transmitting viral diseases to humans. For this reason, the manufacturing process on fish skin is much less harsh and can retain key bioactive characteristics such as omega-3-fatty acids and collagen I structure. This material is cost-effective, so it can be converted into a useful resource and retains key biological characteristics compared to other animal-derived skin technologies.
