Abstract: The present invention provides a biological tissue cutting device that can produce minute fragments of a biological tissue easily and efficiently. The biological tissue cutting device for producing tissue fragments by cutting a biological tissue includes: a first cutting unit configured to form a cut surface extending in a first direction by cutting the biological tissue on a stage; and a second cutting unit configured to form a cut surface extending in a second direction and a cut surface extending in a third direction by cutting the biological tissue on the stage. The planar direction of the cut surface extending in the second direction is a direction crossing the cut surface extending in the first direction, and the planar direction of the cut surface extending in the third direction is a direction crossing the cut surface extending in the first direction and the cut surface extending in the second direction.

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.
