Figure 8. Effect of SkQ1 on endothelial EA.hy926 cell tubular structures formation on Matrigel. The effect of 20 nM SkQ1, and conditioned medium (c.m.) from fibroblasts treated with 20 nM SkQ1. (a) Representative micrograph of matrigel angiogenesis assay; bar, 60 μm; (b-e) analysis of tube formation. Data are presented as mean ± SEM; N=5;*P < 0.05 **P < 0.001 for c.m. from SkQ1-treated versus untreated fibroblasts.
