TFP reduces MC proliferation in vitro. TFP reduced MC proliferation. Quiescent MCs were treated with 10 and 20% FBS in the absence or presence of TFP (5, 10, 15, 20, and 30 μmol/L). Cell viability was assessed using the MTT assay after 12, 24, and 36 h. Data are presented as means ±SD values of 3 independent experiments. (* p<0.05 vs. control, ** p<0.01 vs. control, #
