Fig. 4From: Exosomes from cervical cancer cells facilitate pro-angiogenic endothelial reconditioning through transfer of Hedgehog–GLI signaling componentsAssessment of exosomal uptake in endothelial cells. Fluorescence photomicrographs showing HUVEC after 6 h incubation with SiHa, HeLa, and C33a-derived exosomes (50 μg/0.5 ml) labelled with PKH-67 dye (green). HUVEC were fixed in cold methanol and nuclei were counterstained with DAPI (blue; magnification—630×)Back to article page
