Fig. 5 Development of choriocapillaris is dependent on VEGF-VEGFR2 in zebrafish. A: Confocal micrographs of the choriocapillaris of 5 days post fertilization (dpf) embryos from wildtype (WT), VHL mutant (VHL-/-), hif1aa-/-;hif1ab-/- (HIF1a-/-), Vegfr2b-/- (kdr -/-), Vegfr2a-/- (kdrl -/-) or fli1a:EGFP; Hsp70:Vegfaa-DN zebrafish incubated for 1?h?at 37?°C daily from 1 to 5 dpf (Vegfaa-DN) crossed onto the Fli1a:EGFP background (endothelium shown in green). Yellow arrowheads indicate interstitial foci. Size bars indicates 20??m in each image. B: Quantification of the number of interstitial foci in the experiment shown in A. n = 10?15 embryos, ***:p < 0.001. ns: non-significant.
