Effect of FGF1 on BrdU incorporation: primary osteoblasts and OB1 cells. The cells were starved for 48 h in 0.4% FCS then either untreated (−) or treated with FGF1 (10 ng/ml) and heparin (10 ng/ ml) for 24 h, and BrdU (4 μg/ ml) was added from 18–24 h. 10% FCS was included as a positive control. The data show the percentage of cells incorporating BrdU. Data shown are mean ± SD from a representative experiment.
