Time course effect of p27KIP1-on HCC-9204 cells growth. Cells were seeded at 10\+5 per dish. HCC-9204 cells were induced by 100 μmol/L ZnSO4 at the time indicated. Cells morphology was observed under Nikon Eclipse TE 200 phase-contrast microscopic at 0, 24 and 48 h post addition of zinc. “Uppe r-row” represents pMD-neo transfected cells; “Lower-row” represents pMD- Bak transfected cells. × 200
