Inhibitive effects of quercetin on rabbit tenon capsule fibroblasts proliferation.

To study the inhibitive effects of quercetin (QU) on the fibroblasts proliferation of rabbit Tenon's capsule and its mechanism.Cultured fibroblasts were exposed to different concentrations of QU solution and investigated by microculture tetrazolium (MTT) assay. The effect of QU was observed on cells cycle using the flow cytometer.QU can suppress the proliferation of rabbit Tenon's capsule fibroblasts in vitro and show a dose-time dependent tendency. Flow cytometer results showed 26.92% cell increase in G1 phase, 23.50% decrease in S phase and 3.42% decrease in G2 phase.QU can suppress the proliferation of rabbit Tenon's capsule fibroblasts in vitro and show a dose-time dependent tendency. QU may effect all phase of cell cycle and inhibit cell proliferation by inhibiting G1 phase transitting to S phase and G2 phase.
