Fig. 3: bFGF promoted podocyte re-entry into the cell cycle.

a Schematic diagram of cell cycle detection results after bFGF treatment for the indicated time periods. b The proportion of cells in S phase in different groups; data are from at least three replicates. c Western blotting analysis of CDK4 and cyclin D1 protein expression after bFGF (50 ng/mL) treatment for the indicated times. d Corresponding graph of (C); each bar represents data obtained from there independent experiments. *P < 0.05 vs. control group.
