Figure 1: Comparison of BCL-2 expression in antral follicle granulosa cells. Note: A (group 1), B (group 2), C (group 3) are control groups exposed to 50 μL PBS and observed respectively on day 5, day 10 and day 20. D (group 4), E (group 5) and F (group 6) were the treatment groups exposed to Mab bZP3 (50 μL) and observed respectively on day 5, day 10 and day 20. The BCL-2 expression is indicated by the chromogen brown color in the antral follicle granulosa cells. The observed IRS index of AMH expression of the antral follicle granulosa cells in control groups was stronger than the average score in treatment groups (Immunohistochemistry, 400 × magnification).
