Bone morphogenetic proteins (BMPs) are expressed during osteogenesis and their action is regulated by corresponding BMP inhibitors. Chordin (a well recognized BMP inhibitor) and BMP-2 are expressed during osteogenic differentiation of human mesenchymal stem cells. Chordin inhibition induces human mesenchymal stem cell differentiation and reduces their proliferation by increasing BMP-2 bioavailability. The potential of suppressing BMP inhibitors is emerging as a biological therapeutic target in bone tissue engineering, because it results in an unopposed synergy between the various growth factors that are involved in osteogenesis, within their physiological milieu.
