Fig. 2From: miR-126-3p containing exosomes derived from human umbilical cord mesenchymal stem cells promote angiogenesis and attenuate ovarian granulosa cell apoptosis in a preclinical rat model of premature ovarian failuremiR-126-3p hucMSCs-exosomes could be internalized into OGCs. A. The morphology of cultured OGCs B. Hematoxylin and eosin staining for identification of OGCs. C. Immunohistochemical staining of FSHR for identification of OGCs. D. The red stain indicated PKH26 -labeled miR-126-3p hucMSCs-exosome. E. The blue stain indicated the DAPI -labeled nucleus. F.
