Fig. 3From: Exosome-mediated miR-144-3p promotes ferroptosis to inhibit osteosarcoma proliferation, migration, and invasion through regulating ZEB1The validation of exosome expression, function and downstream miR-144-3p/ZEB1 axis. A TEM micrographs of exosomes. B The NTA indicated the particle size, volume, and concentration of exosomes. C The WB of exosomes characteristic proteins. D The co-culture assay indicated that labeled exosomes can enter OS cells. E The heatmap of exosome microarray. The RT-qPCR results for validation of transfection F miR-144-3p in Group I-IV and G ZEB1 in Group V-VIII. The RT-qPCR results for validation of downstream H ZEB1 in Groups I-IVBack to article page
