Fig. 12From: Cellular and molecular mechanisms of highly active mesenchymal stem cells in the treatment of senescence of rhesus monkey ovaryUltrastructural changes in hGCs after HA-MSC coculture (1000 × and 5000 ×). Nucleus (N), mitochondria (M), and autolysosome (ALS). In cocultured hGCs, chromatin distribution was uniform, mitochondria were still swollen, rough endoplasmic reticulum was slightly expanded locally, and a few autophagosomes could be seen inside the cellsBack to article page
