MSC-Exos uptake in vitro and in vivo. a The internalization of exosomes into CCSMCs was detected by fluorescence microscopy after CCSMCs were co-cultured with PKH26-labeled exosomes for 4 h, 8 h and 16 h, ×200 amplification. B.PKH26-labeled exosomes were observed by immunofluorescence after injected intracavernous, ×200 amplification
