From: TGF-β1 increases proliferation of airway smooth muscle cells by phosphorylation of map kinases
TGF-β1 enhanced serum-induced proliferation of ASMCs. Confluent and growth-arrested ASMCs were treated with 10% FBS in the absence or presence of TGF-β1 (1 ng/ml) for 48 hours and the changes of [3H]-thymidine incorporation (n = 9) and cell number (n = 6) were determined. All values are % of untreated control cultured in 0.2% BSA/DMEM. p values indicated were compared to control (10% FBS only).
