ASMC responses to TGF-β1 and serum in different culture conditions. ASMCs were cultured with DMEM/10% FBS to confluence and then changed to DMEM/0.2% BSA, DMEM/0.5% FBS, or DMEM/10% FBS for 72 hours, followed by treatment with 5 ng/ml of TGF-β1 or 10% FBS for 24 hours prior to [3H]-thymidine incorporation assay. * p < 0.05, *** p < 0.001 compared to control of the same condition. n = 4–6.
