０引言人骨形态蛋白－３（ｈＢＭＰ－３）可诱导多种来源的未分化间充质细胞向软骨细胞和成骨细胞转化，进而形成新骨，而且对软骨细胞也有促进分裂和增殖的作用，促进后者Ⅱ型胶原和氨基多糖（ＰＧ）的分泌．转基因技术和真核表达载体的产生为软骨细胞库建立和开展软骨组...
0 Introduction Human bone morphogenetic protein-3 (hBMP-3) induces the transformation of undifferentiated mesenchymal cells of various origins into chondrocytes and osteoblasts, and then forms new bone, and also promotes the division and proliferation of chondrocytes. Promote the latter type Ⅱ collagen and amino polysaccharide (PG) secretion. Generation of transgenic technology and eukaryotic expression vectors for the establishment of chondrocyte pools and development of ...
