抄録

With flow cytometry, we investigated the effect of basic fibroblast growth factor (bFGF)-induced competence in subcultured endothelial cells (EC) (4—9-passage) of rat thoracic aorta. The cell population in each phase of the cell cycle was determined by a double staining technique with fluorescein isothiocyanate-conjugated mouse monoclonal antibody against the proliferation-associated nucleus antigen Ki-67 and propidium iodide for total DNA content. EC were cultured in medium containing 5% fetal bovine serum (FBS) for 6 days. After serum-starvation for 2 days, the treatment with bFGF (3—10 ng/ml) for 12 hr promoted the entry of cells into the G<SUB>1</SUB> phase from the G<SUB>0</SUB> phase concentration-dependently. bFGF (10 ng/ml) increased the cell population in the G<SUB>1</SUB> phase by 50% of the total EC, compared with the control culture without bFGF. A further 12—15-hr culture with 1% FBS after bFGF treatment promoted the entry of the cell into the S phase. Thus flow cytometric analysis demonstrates that bFGF stimulates the entry of EC into the G<SUB>1</SUB> phase from the G<SUB>0</SUB> phase.
