23 Jul Artificial skin containing human bone marrow mesenchymal stem cell and its construction method
Abstract
The present invention relates to construction process of artificial skin containing human bone marrow mesenchymal stem cell. Skin tissue engineering rack is first constructed with fetus calf or ox tendo achillis as basic material, collagen sponge film through twice enzyme treatments and the mixture of heparin and epidermal growth factor; and human bone marrow mesenchymal stem cell obtained via purifying human bone marrow blood is implanted on two sides of the rack to constitute the artificial skin with bone marrow mesenchymal stem cell on the two sides of and in the internal of the rack. The artificial skin has no antigenicity, high strength, high flexibility, no toxicity to wound, and capacity of inducing wound cell growth and promoting wound healing.
