Effect of exogenous HDGF on BrdU uptake in SMCs. SMCs grown on coverslips in SFM were treated with SFM, 10% FBS, HDGF (100 ng/mL) or vehicle (PBS) for 24 or 48 hours and pulsed with BrdU for 6 hours. BrdU-positive nuclei were counted (n = 4 coverslips per group) and expressed as fold increase over SFM group as mean ± SEM. *P < 0.05 SFM versus FBS or HDGF by one-way ANOVA.
