Fig. 4From: Colorectal cancer-derived small extracellular vesicles induce TGFβ1-mediated epithelial to mesenchymal transition of hepatocytesCRC_sEVs carry TGFβ1 and induce TGFβ1 signaling pathways in hepatocytes. a Western blot analysis of TGFβ1 in SW480 and SW620 cells and derived sEVs. b dSTORM imaging of SW480_ and SW620_sEVs. The graphs on the right report the ratios of the number of each sEV group to the total number of counted sEVs expressed as a percentage. c ELISA showing the effect of trypsin treatment on the presence of TGFβ1 in CRC_sEVsBack to article page
