BMPs play a key role in the transformation of mesenchymal cells into bone and naturally recruit stem cells from the surrounding tissue to initiate the bone formation cascade. BMPs have been the focus of many orthopedic clinical development programs. Along with PDGF-B, BMPs are the only FDA-approved growth factors for healing bone.
In 2001, the first BMP (BMP-7/OP-1) received FDA approval for use in the U.S. (by Stryker) for hard-to-heal long bone fractures. In 2002, Medtronic's INFUSE((R)) (BMP-2) received FDA approval for use in certain spinal fusion procedures and was later expanded to include certain long bone fractures, and dental bone graft applications. Both products use a collagen carrier matrix to provide an osteoconductive environment for bone cells to attach and grow.
Cardium's Orthobiologics Research
Significant pre-clinical research has been conducted and published by researchers and collaborators at Cardium's Tissue Repair Company and the University of Michigan demonstrating the safety and benefits of adenovector-mediated platelet-derived growth factor gene expression in the areas of periodontal tissue engineering and bone-grafting applications. Published data for periodontal tissue engineering include: (1) Platelet-Derived Growth Factor Gene Delivery Stimulates ex Vivo Gingival Repair, (Anusaksathien, et al., Tissue Eng. 2003 August; 9(4): 745-756); (2) Engineering of Tooth-Supporting Structures by Delivery of PDGF Gene Therap
