| Background: In mammalian ovaries, loss of over two-thirds of germ cells happens due to cell death. Nonetheless, the exact mechanism of cell death has yet to be determined. The present basic practical study was designed to detect 3 types of programmed cell death, namely apoptosis, autophagy, and necrosis, in murine embryonic gonadal ridges and neonatal ovaries.Methods: Twenty gonadal ridges and ovaries from female mouse embryos 13.5 days post coitum and newborn mice 1 day postnatal were collected. The TUNEL assay was performed to evaluate apoptosis. The interplay of autophagy was evaluated by immunohistochemistry for beclin-1. Necrotic cell death was analyzed by propidium iodide (PI) staining. The count and percentage of the labeled oocytes in the gonadal ridges and ovaries were evaluated and compared using the independent t test and one-way ANOVA. A P value less than 0.05 was considered statistically significant.Results: We detected TUNEL-positive reaction in the embryonic germ cells and in the small and large oocytes of the neonatal ovaries. The germ cells and small oocytes reacted to beclin-1. PI absorption was detected in the embryonic germ cells and the large oocytes of the neonatal ovaries, but not in the small oocytes. The percentage of the TUNEL-positive and PI-labeled oocytes in the gonadal ridges was significantly higher than that in the neonatal ovaries (P | ||
