Fig. 4From: Plasma-derived small extracellular vesicles unleash the angiogenic potential in head and neck cancer patientsCrystal violet staining of HUVECs co-incubated with sEVs. Crystal violet staining of HUVECs after 24 h of stimulation with sEVs from HNC, NED patients and HD. HUVECs co-incubated with sEVs from HNC patients showed a rather elongated morphology and remained confluent compared to HUVECs with HD sEVs. The control images, HUVECs with PBS (CTRL) and LVES, visualized cobblestone-shaped and attached cells. Magnification = 2.5x, scale = 200 µmBack to article page
