Abstract: The present invention aims to provide a method for producing auricular cartilage tissue having a sufficient thickness and mechanical strength, and auricular cartilage tissue produced by the method for producing auricular cartilage tissue. The present invention provides a method for producing auricular cartilage tissue, including the steps of: seeding auricular chondrocytes onto a non-woven fabric consisting of a bioabsorbable material having an average fiber diameter of 0.90 to 7.00 ?m; and forming a composite of the non-woven fabric seeded with the auricular chondrocytes and a mesh-like framework consisting of a non-bioabsorbable material, and shaping the composite.

Abstract: An artificial heart valve comprising a tubular base body having sinuse(s) of Valsalva and valve cusp(s) provided inside the base body, characterized in that the base body and the valve cusps comprise a bioabsorbable polymer material.

Abstract: A matrix for tissue culture comprising two kinds of sponges having at least one different physical property and/or at least one different chemical property; a method for culturing tissue using said matrix for tissue culture comprising inoculating and culturing first cell on a first sponge, laminating a second sponge thereon, and inoculating and culturing second cell on said second sponge; a method for fixing a cultured tissue comprising placing a cultured tissue in gelatin solution solated by elevating temperature, lowering temperature to gelatinize gelatin to fix the cultured tissue by said gelatinated gelatin; and an artificial skin fixed comprising dermis layer fixed by gelatin and epidermis layer laminated on the dermis layer.

Abstract: A process for preparing a crack-free, dried collagen sponge having a shrinkage factor of up to 14%, including the steps of impregnating crosslinked collagen sponge with an aqueous solution of a hydrophilic organic solvent, freezing the sponge at a temperature of -80.degree. C. or lower, and vacuum-drying the sponge.
