Abstract

It has been discovered that mesenchymal stem cells (MSCs) in a polymeric carrier implanted into a cartilage and/or bone defect will differentiate to form cartilage and/or bone, as appropriate. Suitable polymeric carriers include porous meshes or sponges formed of synthetic or natural polymers, as well as polymer solutions. A presently preferred material is a polyglycolic acid mesh.
