Influence of geniposide on collagen II synthesis of cultured chondrocytes in vitro / 中国组织工程研究

ABSTRACT

BACKGROUND:Chinese herb Cape Jasmine Fruit can activate the chondrocytes and geniposide is an important component in this herb. OBJECTIVE:To investigate the effect of geniposide on col agen II synthesis in rat chondrocytes cultured in vitro. METHODS:Rat chondrocytes were separated and cultured in vitro. The chondrocytes were then interfered with 25, 50 and 100 mmol/L geniposide. Normal control group was also set. Col agen II mRNA and protein expression was detected with semi-quantitative RT-PCR and western blot analysis, respectively. RESULTS AND CONCLUSION:RT-PCR and western blot analysis results showed that, geniposide at 25, 50 and 100 mmol/L increased the col agen II mRNA and protein expression (P<0.01). Geniposide can promote the synthesis of col agen II in rat chondrocytes cultured in vitro.
