Bone morphogenetic protein 2 or BMP-2 belongs to the TGF-β superfamily of proteins.[4]


BMP-2 like other bone morphogenetic proteins,[5] plays an important role in the development of bone and cartilage. It is involved in the hedgehog pathway, TGF beta signaling pathway, and in cytokine-cytokine receptor interaction. It is also involved in cardiac cell differentiation and epithelial to mesenchymal transition.

BMP-2 and BMP-7 are osteoinductive BMPs: they have been demonstrated to potently induce osteoblast differentiation in a variety of cell types.[6]


Bone morphogenetic protein 2 has been shown to interact with BMPR1A.[7][8][9][10]

Clinical use and complications

Bone morphogenetic protein 2 is shown to stimulate the production of bone.[11][12] Recombinant human protein (rhBMP-2) is currently available for orthopaedic usage in the United States.[13] Implantation of BMP-2 is performed using a variety of biomaterial carriers ("metals, ceramics, polymers, and composites"[14]) and delivery systems ("hydrogel, microsphere, nanoparticles, and fibers"[14]). While used primarily in orthopedic procedures such as spinal fusion,[15][16] BMP-2 has also found its way into the field of dentistry.[17][18][19]

The use of dual tapered threaded fusion cages and recombinant human bone morphogenetic protein-2 on an absorbable collagen sponge obtained and maintained intervertebral spinal fusion, improved clinical outcomes, and reduced pain after anterior lumbar interbody arthrodesis in patients with degenerative lumbar disc disease.[15] As an adjuvant to allograft bone or as a replacement for harvested autograft, bone morphogenetic proteins (BMPs) appear to improve fusion rates after spinal arthrodesis in both animal models and humans, while reducing the donor-site morbidity previously associated with such procedures.[16]

A study published in 2011 noted "reports of frequent and occasionally catastrophic complications associated with use of [BMP-2] in spinal fusion surgeries", with a level of risk far in excess of estimates reported in earlier studies.[20][21] An additional review by Agrawal and Sinha of BMP-2 and its common delivery systems in early 2016 showed how "problems like ectopic growth, lesser protein delivery, [and] inactivation of the protein" reveal a further need "to modify the available carrier systems as well as explore other biomaterials with desired properties."[14]
