Upregulation of arterial Notch reporter tp1:GFP expression in SIA progenitors. Confocal microscope timelapse images of Tg(etv2:mCherry);Tg(tp1:GFP) embryos beginning at approximately 60 hpf. (A-C) Endothelial progenitors in the SIA express etv2:mCherry as they migrate from the PCV, but arterial specifc Notch reporter tp1:GFP expression is gradually upregulated as SIA progenitors coalesce into a blood vessel. Box indicates SIA.
