Fig. 3From: Concentrated exosomes from menstrual blood-derived stromal cells improves ovarian activity in a rat model of premature ovarian insufficiencyCell proliferation and apoptosis of rat ovaries cultured in vitro. a EdU staining of ovaries (red) and statistics of fluorescence intensity. Nuclei were stained by using DAPI (blue, × 100, n ≥ 4). b TUNEL staining of apoptosis (green) and statistics of fluorescence intensity. Nuclei were stained by using DAPI (blue, × 100, n ≥ 4). c RT-PCR analysis of Bcl2, Bad, Bax, and Casp8 in ovaries (n = 6). Data were represented as mean ± SD, *p < 0.05, **p < 0.01, ***p < 0.001Back to article page
