Fig. 6From: Exosomes derived from mature chondrocytes facilitate subcutaneous stable ectopic chondrogenesis of cartilage progenitor cellsThe effects of exosomes on HUVEC migration and tube formation. a, c Migration of HUVECs exposed to different exosomes for 6 h and a summary of the migrated cells. Cells are colored by violet, scale bar = 200 μm. b, d, e. HUVEC tube formation was studied by growing cells in Matrigel and quantitative analysis of total tube length and junction number after 3 h. *P < 0.05, compared to negative control (NC), ▲P < 0.05, compared to positive control (PC), #P < 0.05, CC-Exos compared to the BMSC-Exos groupBack to article page
