Osteoinductivity of partially purified native ostrich (Struthio camelus) bone morphogenetic protein: comparison with mammalian species.

Bone morphogenetic proteins (BMPs) are members of the TGF-beta superfamily. They are capable of inducing ectopic bone formation. Until now, the main interest has been focused on mammalian osteoinductive BMPs, and there are no reports of native BMP extracts of birds.
