Fig. 1From: Exosomal lncRNA UCA1 modulates cervical cancer stem cell self-renewal and differentiation through microRNA-122-5p/SOX2 axisIdentification results of exosomes. a The morphology of exosomes observed under a transmission electron microscope (× 200,000, 50 nm). b western blot analysis detected expression of CD63 and CD81. c The size distribution and concentration of exosomes were determined by NTA. Measurement data were depicted as mean ± standard deviation, comparisons between groups were conducted by independent sample t test, the experiment was repeated three timesBack to article page
