Exo-HIF-1α rescued the impaired angiogenesis of hypoxia-injured HUVECs. a Representative figures of HUVECs up-taking DiI-labeled exosomes. Bar: 100 μm. b HIF-1α mRNA expression level in 4 groups (n = 3). c Tube structure on Matrigel could be observed 6 h after seeding 4 groups of HUVECs. Bar: 500 μm. d, f Quantitative assessment of the total number of meshes number and tube length (n = 3). *P < 0.05, **P < 0.01, ***P < 0.001
