It is particularly useful for superficial partial-thickness facial burns. The biological skin substitutes have a more intact extracellular matrix structure, while the synthetic skin substitutes can be synthesised on demand and can be modulated for specific purposes. Development of biodegradable electrospun scaffolds for dermal replacement. The autograft take rate of Artificial dermis for major burns. Burn wound care is important to avoid infection and help the healing process. As the skin allograft can increase vascularity in the wound bed, including promoting angiogenesis with enhanced capillary ingrowth on the wound bed, it has been used for burn wound bed preparation. Sheridan RL, Moreno C. UC Davis.
Among the indications for skin grafting are promotion of accelerated .

From the name, cultured skin substitutes indicate grafting materials that have both. Conventionally, autologous split or full-thickness skin graft have been Skin substitutes are heterogeneous group of wound coverage materials that aid in.
Burns; ; 36 — It should maintain its three-dimensional structure for at least 3 weeks to allow ingrowths of blood vessels, fibroblast and coverage by epithelial cells.

This process should occur without massive foreign body reaction as this process would increase the inflammatory response, which may be associated with profound scarring. Hyalomatrix: A temporary epidermal barrier, hyaluronan delivery, and neodermis induction system for keratinocyte stem cell therapy.

Skin grafts are a major component of more severe wound healing regimens. These grafts. Skin grafting is a type of graft surgery involving the transplantation of skin. The transplanted skin; xenograft or heterograft). Prosthetic: Lost tissue is replaced with synthetic materials such as metal, plastic, or ceramic (prosthetic implants).

|While the synthetic skin substitutes can be synthesised on demand and can be modulated for specific purposes with increased control over scaffold composition, the biological skin substitutes have a more intact and native ECM structure which may allow the construction of a more natural new dermis.
The dermis left behind at the donor site contains hair follicles and sebaceous glandsboth of which contain epidermal cells which gradually proliferate out to form a new layer of epidermis. Its indications are full thickness or deep dermal burn wounds and chronic wounds. The use of MatriDerm in early excision and simultaneous autologous skin grafting in burns— a pilot study. The skin substitutes provide rapid wound coverage solution that may require less vascularised wound bed, increase in the dermal component of healed wound, reduce or removed inhibitory factors of wound healing, reduced inflammatory response and subsequent scarring.

The donor site may be extremely painful and vulnerable to infection. The scaffold delivers hyaluronan to the wound bed, and the silicone membrane acts as a temporary epidermal barrier. The epithelialisation of the wound bed is also accelerated when skin allograft is applied.
The GPA is more popular and commonly used in clinical practice.
