Mineral evolution of bone.

abstract：:Chondrogenic differentiation of mesenchymal stem cells (MSCs) is critical for successful cartilage regeneration. Several methods have been developed to attempt to chondrogenic differentiation, because chondrogenic differentiated cells can form stable cartilage and induce expression of a cartilage-specific phenotype. I...
