Method for producing scaffold for cell proliferation having structure memory characteristics

摘要

A method for producing a scaffold for cell growth having structure memory characteristics, comprising the steps of producing a fibrillar or cocoon-like decellularized tissue matrix material, and an acidified hydrogel decellularization A step of producing tissue matrix particles and mixing the produced microfibrous or cage-like decellularized tissue matrix material and acidified hydrogel-like decellularized tissue matrix particles in a ratio, Performing injection, freezing treatment, and radiation treatment, and finally producing a porous cell growth scaffold that can be stored at room temperature. The scaffold produced by the production method is a porous cell growth scaffold that does not require chemical cross-linking, has biological activity, has stable three-dimensional structure and structure memory characteristics, and has excellent biocompatibility and completeness. It is biodegradable, supports cell proliferation, tissue and organ growth in vivo and in vitro, and is suitable for soft tissue wound and defect repair. [Selection] Figure 5
