Figure 1.

Comparison of different matrices used for aortic ring assay. The following four different matrices were compared using a complete medium: chicken egg white (A), collagen from bovine skin (B), jellagel (C), and matrigel (D). The parameters shown in bar charts are the calculated vessel area (E), maximal outgrowth radius (F), and endpoints per aortic ring (G). Scale bars 500 μm (A–D). Data shown are means ± SD with individual values (n = 6). Groups were compared using nonparametric Kruskal–Wallis test (ns: not significant; *** p < 0.001).
