bone matrix
8.?orcine bone matrix gelatin combined with porcine bone morphogenetic protein(pBMG-pBMP) were implanted into the muscles of mice in order to obtain double osteogenic roles of pBMG and pBMP. The results were compared with those of spongia gelatini、pBMG 、 pBMP and anorganic bone combined with pBMP(AOB-pBMP) which were respectively implanted into the muscles of mice.
