Abstract:
1. A process for producing a basement membrane specimen or an artificial tissue which can be transplanted while maintaining the structure of a basement membrane wherein the process comprises the following steps: (a) Providing an adsorptive polymer having a hydrophobic linear carbon skeleton and a functional group which can react with a protein in a molecule; (b) Temporarily adhering a protein support structure to a plastic surface through the adsorptive polymer by hydrophobic bonding; (c) Forming a basement membrane specimen or an artificial tissue on the protein support structure which is temporarily adhered to the plastic surface through the adsorptive polymer by hydrophobic bonding, wherein the basement membrane specimen or the artificial tissue is prepared by culturing cells having an ability to form a basement membrane; and (d) Mechanically detaching the protein support structure supporting the basement membrane specimen or the artificial tissue from the plastic surface.
