HCPT-EVs are more capable of repressing fibroblast proliferation and viability boosted by TGF-β1. Rat fibroblasts were treated with Unprimed EVs or HCPT-EVs (100 μg/mL) in the presence of TGF-β1 (2 ng/ml) for the indicated times and for 48 h in a live/dead assay. a Cell proliferation curve of fibroblasts plotted according to CCK-8. b Proliferation rate relative to the control. c Representative dead/live staining of fibroblasts. d Dead/live rate of fibroblasts. *P < 0.05, ***P < 0.001; ns, not significant
