Blood vessel formation (angiogenesis) is observed at the same time. Step 5: Bone formationĪs the sponge degrades or dissolves, these stem cells differentiate into osteoblast and begin to form trabecular bone and/or cartilage. The researchers concluded that BMP-2, BMP-6, and BMP-9 may be the most potent agents to induce osteoblast lineage-specific differentiation of mesenchymal stem cells. Alkaline phosphatase activity - a measure of the amount of new bone formation - was significantly increased in all three cell lines by BMP-2, BMP-6, and BMP-9. 20 Three cell lines, representing the different stages of osteoblast differentiation, were each tested. 3-19Ī 2003 in-vitro study compared the bone-forming activity of 14 recombinant human bone morphogenetic proteins. 1 Pre-clinical studies have shown that rhBMP-2 can cause the differentiation of precursor cells into osteoblasts. 2, 7 In-vitro studies of rhBMP-2 support the fact that differentiation of mesenchymal stem cells into bone-forming osteoblasts plays an essential role in the induction of new bone. 3-7 Step 4: Differentiationīinding to specific receptors on the surface of the MSC, rhBMP-2 causes them to differentiate into bone-forming cells. In-vitro studies have shown that rhBMP-2 can increase the proliferation of several multipotent cell lines, which can differentiate into osteoblasts, or bone-forming cells. The mesenchymal stem cells around the rhBMP-2/ACS implant increase in number. Mesenchymal stem cells (MSC) move from bleeding bone, muscle, and the periosteum to infiltrate the implant. This cell migration stimulated by a chemical response is called chemotaxis.

Step 2: Chemotaxisīone-forming cells migrate to the area of the rhBMP-2/ACS implant. Only when they're used together do they initiate the bone induction process. Neither the rhBMP-2 nor the ACS can produce new bone tissue independently. Spine Health.When rhBMP-2 is placed on an ACS and implanted in the body, it produces new bone tissue at the site of implantation. Anterior lumbar interbody fusion (ALIF) surgery.

These proteins have a large role in forming cartilage and bone in the body. Donated bone carries a risk of infection or disease, and the quality of the bone cannot be controlled.īMP occurs naturally in the body and was first discovered by Dr. Doctors typically take bone from another part of the patient’s body, use donated bone or use synthetic bone.Īfter the fusion, the individual vertebrae form one solid bone, eliminating irritation of nerves in the spine.īy using synthetic bone, doctors don’t have to harvest bone from another part of the body, such as the hip. In spinal fusion, doctors surgically fuse together the individual damaged bones of the spine, called vertebrae. Analysts predict a 7.5 percent annual growth rate by 2019 and the market is expected to reach $6.4 billion by 2024. spinal implant market is a multibillion-dollar industry and continues to grow.
