Method for producing a porous three-dimensional support using the animal tissue powder of the present invention, the step of pulverizing the animal-derived tissue, before or after the pulverization of the animal-derived tissue, or at the same time as the powdering, and Forming the powder of the decellularized animal-derived tissue into a porous three-dimensional support using a particle extraction method. Porous three-dimensional scaffolds according to the present invention have various sizes, porosities, shapes, and structures, and can be clinically applied for therapeutic or use purposes, and have no immune rejection or inflammatory response during transplantation, and are biocompatible. The cartilage regeneration effect is superior to collagen and other synthetic polymer supports in cartilage regeneration. In addition, it provides an environment suitable for the movement, growth, and differentiation of cells, and contains components and growth factors suitable for cartilage regeneration, and has excellent biocompatibility, biodegradability, and three-dimensional structure. It can be usefully used as a support. |
