Supplementation of bFGF promotes the proliferation of N-PVCs and GDM-PVCs.

(A) Representative images of N-PVC and GDM-PVC cultured in the presence or absence of bFGF for 4 days. Scale bars. 500 μm. (B) N-PVCs (black bars) and GDM-PVCs (gray bars) at passage 4 were plated at a density of 4 × 10⁴ cells and treated with 20 ng/ml of bFGF for 4 days. (C) Changes of cell cycle compartments by bFGF treatment were estimated by BrdU incorporation assay. *p < 0.05. **p < 0.01. Error bars indicate SD.
