Process For Producing Collagen Sponge, Process For Producing Artificial Skin, Artificial Skin And Cell Tissue Culture Substrate

摘要

It is an object of the present invention to provide a method for producing a collagen sponge and a method for producing an artificial skin which can give a high yield through simplified steps, no inferior goods being produced in the finally-obtained collagen sponges and artificial skins; and an artificial skin and a substrate for tissue engineering which respectively comprise a collagen sponge produced by the method for producing a collagen sponge. The present invention is a method for producing a collagen sponge, wherein a diluted collagen solution having a pH adjusted by use of acetic acid is used.
