ABSTRACT:
A method for stimulating chondrocyte proliferation and inhibiting chondrocyte differentiation along the endochondral developmental pathway is provided comprising contacting condrocytes with an effective amount of Platelet-Derived Growth Factor (PDGF) such as PDGF-BB, PDGF-AA OR PDGF-AB in the substantial absence of growth factors which promote cell differentiation. This allows such cells to be multiplied in culture for loading onto a scaffolding material and implanting into a cartilage or bone wound.
