Movie 7

Wnt5a^GOF hearts display morphological defects, reduced ventricular trabeculation and increased percentage of NkxECs. Embryonic hearts from control (left) and Wnt5a^GOF (right) hearts were isolated at e12.5, serially sectioned and imaged by confocal microscopy. Nuclei (blue), VEGFR2^GFP+ ECs (green) and Nkx2.5^Cre:tdTomato⁺ cells (red) are shown.
