Compositions and methods utilizing TGF-.beta. and demineralized bone matrix are described that are capable of inducing the formation of useful non-resorptive bone. Bone, formation is stimulated by the synergistic activity of a TGF-.beta. molecule such as TGF-.beta.1 or, TGF-5.beta. with a HCI-treated demineralized bone matrix. Normal hard non-resorptive, bone development is stimulated and can be utilized in the treatment of fractures skeletal, defects, surgical repairs and skeletal reconstructions such as in maxillofacialreconstructions.
