Effects of ExoC6-cer on the functions of HUVECs. a The proliferation of HUVECs was tested after 48 h of incubation with 40 µg/ml of ExoC6-cer by MTT assay. b Migration assays were performed to explore the effects of ExoC6-cer on the migration abilities of HUVECs, which was photographed under a microscope at × 100 magnification (left-hand panels). The mean wound width was measured and the images are representative of three independent experiments (right-hand panel). c Tube formation of HUVECs treated differently was photographed under a microscope at × 100 magnification (left-hand panels). All the experiments were performed in triplicates. Three fields were counted under the microscope. The images are representative of three independent experiments. Mean tube length was quantified by image pro-plus software (right-hand panel). (*P < 0.05)
