Movie 6

β-catenin gain of function embryos at e9.0 and e9.5 show reduced vascular density. Embryos from wild type and heterozygous β-catenin gain of function embryos were serially sectioned and imaged by confocal microscopy. Nuclei (blue), VEGFR2^GFP+ ECs (green) and Nkx2.5^Cre:tdTomato⁺ cells (red) are shown.
