Representative live micrograph of transgenic zebrafish embryos Tg (fli1:EGFP)y1 at 72 hpf showing the effect of compound 4a on blood vessel formation. (A–D) Control embryos showing the number and structure of sub-intestinal angiogenic blood vessels in the yolk area as well as the intersegmental or intersomatic angiogenic blood vessels. (C,D) The structure and number of sub-intestinal angiogenic blood vessels in the yolk area and the intersegmental or intersomatic angiogenic blood vessels, which were not affected by exposure to compound 4a.
