Cellular uptake of PKH67-labeled MSCs-Exo by 4T1 and TUBO cell lines.

Note: Intracellular PKH67-labeled MSCs-Exo were detected in 4T1 and TUBO cells by confocal laser scanning microscopy after 24 hours of co-culturing (inset is a higher magnification image).

Abbreviation: MSCs-Exo, mesenchymal stem cell-derived exosomes.
