Objective To study the main biological characteristics of chondrocytes after gene-transfected by HGFcDNA labled with GFP.Methods The chondrocytes of the rabbit condylar were derived from rabbits,and were cultured to the second generation in vitro,before HGFcDNA transfected the cells.The capacity of cell proliferation was tested by MTT.The differences of type II collagen were tested by SABC immunohistochem of the type II collagen after infected;the mRNA levels were tested by in situ hybridization of the type...
