Uptake of PKH67-labeled MenSCs-EXO by granulosa cells In-vitro. Exosomes, purified from condition media of MenSCs culture, were labeled with PKH67 dye and co-cultured with primary culture of granulosa cells for 24 h. Green fluorescence indicates the successful uptake of PKH67-labeled MenSCs-EXO by the granulosa cells, while blue fluorescence represents nuclear staining with Hoechst. 100 × magnification; bars = 100 μm
