Fig. 1From: Downregulation of tumor‐derived exosomal miR-34c induces cancer‐associated fibroblast activation to promote cholangiocarcinoma progressExosomes secreted from cancer cells regulate activation of fibroblasts. a qRT-PCR analysis of expression of pro-inflammatory genes—IL-1β, IL-6, and IL-8—in CCC-HSF-1 cells treated with exosomes from HuCCT-1 or HIBEC cells. b Western blotting analysis of fibroblast activation proteins—α-SMA and FAP. c Migration assay for CCC-HSF-1 cells treated with equal quantities of exosomes derived from tumor or normal cells; Scale bar, 50 μm. d Confocal imaging of Dio-labeled (green) exosomes incubated with Dil-labeled (red) fibroblasts; Scale bar, 10 µm.
