Abstract:
A cell growth scaffold having a structural memory property is a porous material prepared by proportionally mixing a micro-fibrous or flocculent acellular tissue matrix material with an acidification treated, granular hydrogel-like acellular tissue matrix material, followed by injection molding, freezing and extruding, re-interweaving and radiation processes. This scaffold has no chemical cross-linking, and has biological activity, a stable three-dimensional structure and a structure memory property. This scaffold has an excellent biocompatibility and complete biodegradability, and supports the growth of cells as well as the growth of tissues and organs in vivo and in vitro, thereby being suitable for repair of human soft tissue traumas and defects.

Claim (Index 1):
A cell growth scaffold having a memory property structure, comprising a matrix material for cell growth, wherein, said scaffold is formed by mixing, in respective dry weight mass proportions, a micro-fibrous or flocculent acellular tissue matrix material having a fibre diameter of 2-250 microns and a length of 100-3000 microns with an acidification-treated, hydrogel-like acellular tissue matrix material having a particle diameter of 2-150 microns, followed by injection molding, freezing and extruding, re-interweaving and radiation processes; wherein, the matrix material for cell growth is a matrix material of said cell growth scaffold, the content of the total acellular tissue matrix materials in the matrix material of said cell growth scaffold is 10-100 mg/cm3, the total porosity of said cell growth scaffold is 90-99%, and, the porosity of said cell growth scaffold with pore size larger than 25 microns is 80-98%.
