Fig. 1 Cell cycle distribution in differentiating bovine bone-marrow
mesenchymal stem cells (BMSCs) following treatment with various
concentrations of epigallocatechin-3-gallate (EGCG) for 2, 4, or 6 days.
EGCG induced cell arrest at the gap 2/mitosis (G2/M) phase in a timeand
concentration-dependentmanner. The induction of differentiation cell
cycle distribution was assessed by DNA staining by using propidium
iodide and subsequent fluorescence–activated cell sorting (FACS)
analysis. The cell cycle distribution did not differ during the S phase
