HCPT inhibits fibroblast proliferation. a Dose-dependent effects on fibroblasts after treated with different concentrations of HCPT, the viability was determined by CCK-8 assay, *P < 0.05, **P < 0.01 vs 0 μ/ml group. b-c The expression of Cyclin D1and PCNA was determined by western blot analysis in human fibroblast cells treated with 0, 0.05, 0.5, 0.1, and 4 μg/mL HCPT, *P < 0.05 vs 0 μ/ml group. β-actin was used as a control. These experiments were performed in triplicate
