T. Gao et al., COMPOSITES OF BONE MORPHOGENETIC PROTEIN (BMP) AND TYPE-IV COLLAGEN, CORAL-DERIVED CORAL HYDROXYAPATITE, AND TRICALCIUM PHOSPHATE CERAMICS, International orthopaedics, 20(5), 1996, pp. 321-325
Few studies have been performed to investigate the characteristics of
native Pone Morphogenetic Protein (BMP). We derived 5.85 g of native m
oose BMP from 102 kg of fresh moose bone and performed chromatographic
studies to characterise its structure. WE found the BMP molecule to h
ave a molecular weight of 11 - 700 kDa. To investigate the ideal local
delivery system for BMP we used porous discs as a carrier: These were
implanted into 132 mice. The volume of new bone formed was evaluated
by means of histological specimens, radiographs and isotope studies. T
he best results were obtained by implanting porous discs (coral and ce
ramic) with type IV collagen and BMP. We suggest that this is the best
delivery system for future experiments regarding the acton of BMP.
