The tissue engineering skin is officially registered in China and has 4 independent organizational engineering products. The Chinese tissue engineering industry has been internationally first.
Tissue engineering skin is mainly obtained by collecting fresh and normal postoperative skin, digesting, separating and culturing in vitro, obtaining epidermal cells and dermal fibroblasts, amplifying them in large quantities, establishing different uses according to cell type and algebra. The cell bank, and then the epidermal cells and dermal fibroblasts are combined with the bovine collagen scaffold to re-form a certain shape and function, and have vital living tissue skin. With only a small fingernail-sized human skin tissue, hundreds of millions of "active skin" can be cultured.
As the only successful product in China's tissue engineering research, this factory-produced "artificial skin" called "Ai Skin" contains living cells, not only with dermis and epidermis, but also directly for various skin wounds. The clinical application of the patient is very simple. As long as the artificial skin is applied to the affected area, and the wound surface after the repair, the Zui will eventually be replaced by the body's own tissue.
Tissue engineering research is one of the major hotspots in the field of life science research in the 21st century after cell biology and molecular biology. At present, clinically used skin grafts, in addition to the use of autologous skin, conventional dressing plus drug treatment methods, because of no biological activity, no significant promotion of wound healing, can not fundamentally solve the problem of color, texture, especially skin healing .
China's first artificial skin is about to be industrialized
At the 10th high-tech fair held here, Shaanxi Aierfu Tissue Engineering Co., Ltd. and the Fourth Military Medical University Stomatological Hospital signed the "Organizational Skin Technology Transfer Agreement", which is expected to be completed on July 1, 2009. 10,000 square centimeter tissue engineering skin production line construction.
