TUNEL assay for apoptosis of cells with or without progesterone receptor transfection after adding progesterone 100 μM. (A) FE25, scale bar = 100 μm. (B) F25-vector, scale bar = 100 μm. (C) FE25-PRA, scale bar = 100 μm. (D) FE25-PRB, scale bar = 100 μm. *** p < 0.001 compared to control (ctrl). Progesterone treatment increased TUNEL+ cells in all 4 cell lines. TUNEL, terminal deoxynucleotidyl transferase dUTP nick end labeling; PRA, progesterone receptor A; and PRB: progesterone receptor B. P4: progesterone.
