Osteogenic proteins, also referred to as BMPs, are a family of bone ma
trix polypeptides isolated from a variety of mammalian species, These
proteins are members of the transforming growth factor-beta superfamil
y of molecules that contain a highly conserved 7 cysteine transforming
growth factor-beta domain in their C-termini, Use of recombinantly pr
oduced human osteogenic protein-1, also referred to as BMP-7, implante
d in conjunction with bovine bone derived Type 1 collagen or various n
onproteinaceous biodegradable carriers into surgically created large d
iaphyseal segmental defects in animals leads to the regeneration of ne
w bone that is fully functional biologically and biomechanically, Furt
her study has shown that osteogenic protein-1 can be used as a bone gr
aft substitute to promote spinal fusion and to aid in the incorporatio
n of metal implants, Finally, osteogenic protein-1 shows promise as an
agent for repair of osteochondral defects.
