Figure 6. Matrigel-based tube-like formation assays. (A) Representative images (10x) of angiogenesis under each condition; (B) Quantification of angiogenesis as the number of nodes formed after 4 h of incubation with iMSC-EVs. Data are normalized by the negative control. Data from three independent experiments with 4 replicates/condition. Comparison between groups was performed by one-way ANOVA followed by the Kruskal-Wallis test. Error bars represent SD. ns P > 0.05, * P < 0.05.
