Trabecular bone-derived human mesenchymal stem cells

摘要

The present invention discloses an in vitro engineered osteochondral graft comprising a porous matrix block, more particularly, a porous polylactic acid polymer block, press-coated with mesenchymal stem cells (MSCs), wherein a cartilage layer is formed on the surface of the matrix block. This invention may be used for treating articular cartilage defects.
