23 Jul Construction method for skin tissue engineering rack containing epidermal growth factor
Abstract
The construction process of skin tissue engineering rack containing epidermal growth factor with fetus calf or ox tendo achillis as basic material includes dewatering, defatting, primary enzyme treatment to reduce the covalent bond among tissue fibers, dialysis, secondary enzyme treatment to remove antigenic determinant, dissolving with acetic acid to obtain no-antigenicity collagen solution and collagen sponge film, soaking in propanetriol to adsorb, drying, mixing water solution of heparin and acetic acid, water solution of epidermal growth factor and propanetriol wetted collagen sponge film, and final freeze drying. The rack has no antigenicity, high strength, high flexibility, convenient operation implantation, no toxicity to wound, and capacity of inducing wound cell growth and promoting wound healing.
