Exosomes uptake efficiencies by HepG2 cells

(A): Representative fluorescence microscope images (merged) of HepG2 cells co-cultured with PKH67 labeled exosomes derived from HepG2 cells, HeLa cells, K562 cells, and Jurkat cells respectively for 24 h. Blue is the DAPI stained nucleus. (B): Flow cytometric analysis of exosomes uptake efficiencies of HepG2 cells; HepG2 cells were co-cultured with the PKH67 labeled exosomes derived from HeLa cells, K562 cells, HepG2 cells and Jurkat cells respectively for 24h and analyzed by flow cytometry. (C): The uptake rate and MFI of each group is summarized in the bar graph. Each column represents the mean ± SD from four independent experiments. One-way ANOVA and LSD test, *: p value of HepG2 group was less than 0.05 compared with the other groups (n = 4).
