Circulating Exosomal miR-144-3p from Crohn’s Disease Patients Inhibits Human Umbilical Vein Endothelial Cell Function by Targeting FN1

Figure 4

Circulating exosomes from CD patients entered into the HUVECs. Nuclei were labeled with DAPI (blue), the cytoskeleton was labeled with phalloidin (green), exosomes were labeled with PKH-26, PKH26-labeled exosomes (red) were incubated with HUVECs, and PKH26-labeled exosomes were detected inside the HUVECs as visualized using a fluorescence microscope, confirming that the exosomes entered into the cells.
