Inhibitory effect of TGF-β1 on cell proliferation and cell cycle.
Inhibitory effect shown by 3H-TdR incorporation (A) and propidium iodide staining (B) in asychronized 32D cells. 32D cells were cultured at different indicated concentrations of TGF-β1 for 48 hours, after which 3H-TdR uptake was performed. Cells used for cell-cycle analysis were treated with 20 ng/mL TGF-β1 and collected at 48 hours.
