Abstract

See full text

According to the present invention, there are provided a membrane for immunoisolation, including: a porous membrane that contains a polymer, in which the porous membrane includes a layered compact portion where a pore diameter is the smallest within the membrane, and a pore diameter continuously increases in a thickness direction from the compact portion toward at least one surface of the porous membrane; a chamber for transplantation for enclosing a biological constituent therein, including the above-described membrane for immunoisolation on at least a part of a surface forming an inside and an outside of the chamber for transplantation; and a device for transplantation, including the above-described chamber for transplantation enclosing the biological constituent therein. In the membrane for immunoisolation of the present invention which can be manufactured at low costs, a deterioration in substance permeability is unlikely to occur.
