Abstract:
In this study, we demonstrated that bone marrow stromal cells maintained on type I collagen matrix induced bone in vivo. The formed bone contained bone marrow, and the process of bone formation occurred without cartilage formation. Bone marrow stromal cells differentiated into osteoblasts on type I collagen matrix in vitro, but types II, III, and V collagens did not possess this activity. These findings imply that type I collagen matrix offers a suitable environment for the induction of osteoblastic differentiation in vitro and osteogenesis in vivo.
