  • The numbers are presented as the mean value per 100 μm2 of ER area ± SD. The values in all mitotic groups were statistically different from interphase (P < 0.05), except in those marked with *. INTER = interphase (n = 11 cells), PRO = prophase to prometaphase (n =16 cells), META=metaphase (n = 9 cells), ANA = anaphase (n = 9 cells), TELO = telophase (n = 7 cells).
