Methods: Chondrocytes from the knee joints of New Zealand white rabbits were cultured. bFGF or HA or both were added into the culture medium respectively, and the proliferation of the chondrocytes was measured with MTT 3 (4, 5 dimethylthiazol 2 yl) 2, 5 diphenyl tetra zolium bromide. (MTT, Sigma, M2128). Results: Basic fibroblast growth factor (10 ng/ml) with low concentration of fetal bovine serum in the culture medium promoted the proliferation of chondrocytes significantly, and this effect reached its maximum when concentration of bFGF reached 50 ng/ml. HA itself had no effect on the proliferation of chondrocytes. However, when bFGF was used in combination with HA, especially when the concentration of bFGF was 50 500 ng/ml and that of HA was 10 50 ng/ml, the effect on the proliferation of chondrocytes was much more than when bFGF or HA was used alone. Conclusions: bFGF can promote the proliferation of chondrocytes. HA, which has no effect on the proliferation of the cells, can maintain a normal growth of chondrocytes. When bFGF is used in combination with HA, more proliferation is obtained.展开更多
