CaSki-Exo promote invasion and migrasion of CaSki cells. a The uptake of CaSki-Exo by CD133⁺CaSki cells observed by a confocal microscope (× 400, 25 μm). b The expression of UCA1, miR-122-5p and SOX2 mRNA detected by RT-qPCR. c Expression of SOX2, OCT4 and Nanog protein detected by western blot analysis. d and e Scratch test tested would healing distance. f and g Invasion and migration ability of cells tested by Transwell assay. N = 3, * P < 0.05 vs. the control group. Measurement data were depicted as mean ± standard deviation, comparisons between groups were conducted by independent sample t test
