| 摘要 |
The present invention relates to a method for preparing a cell-derived extracellular matrix membrane, more particularly, to a method for preparing a chondrocyte-derived ECM membrane, the method comprising the steps of forming a suitable thickness of ECM membrane by culturing chondrocytes derived from animal cartilage at a high concentration in vitro, and drying it after decellularization process. The cell-derived ECM membrane scaffold according to the present invention is composed of extracellular matrix secreted by chondrocytes so that the membrane has excellent biocompatibility as well as an immune-previlage effect specific to cartilage. Since the membrane also has a suitable compressive strength, it can be used to replace periosteum for cartilage regeneration or artificial collagen membrane and used as dura mater transplant material, a natural ECM membrane for treating skin loss, materials for cell transplantation and a growth factor delivery vehicle.
