Uptake of visualized exosomes under a confocal laser scanning microscope. (A) Exosomes from NB1RGB cells were stained with the SYTO RNA Select Reagent (SYTO). HaCaT cells and NB1RGB cells were treated with exosomes derived from NB1RGB cells (NB1RGB exo). Note that immuno-reaction for SYTO (in green) was not evident in these cells. (B) NB1RGB exo or EBI3 exo were stained with SYTO. Note that accumulated SYTO staining was detected in EBI3 exo.
