L-EVs and S-EVs isolated from the conditioned medium of P29 and A11 cells. (a) Reflection images of L-EVs and S-EVs. Scale bars: 10 μm. (b) PCR analysis of the presence of mtDNA ND6 gene in L-EVs and S-EVs. (c) Localization of L-EVs and S-EVs added to P29 or A11 cells. P29 or A11 cells were incubated with PKH67-labeled L-EVs or S-EVs for 24 h and observed under a laser confocal microscope. Dashed lines represent the outline of the cells. Scale bars: 20 μm
