Phenotype Image Detail
Caption A & B: Transverse sections of E10.5 Ubr1tm1Avar/Ubr1tm1Avar Ubr2tm1Ytkw/Ubr2tm1Ytkw (B) and littermate control (A) embryos stained for neurofilaments. C-F: Hematoxylin/eosin stained transverse sections of double homozygous embryos (D & F) and littermate control embryos (+/+ wild type in C; double heterozygous control in E) at ED10.5 (C & D) and ED11.5 (E & F). G & H: Dorsal views of ED11.5 double homozygous (H) and double heterozygous control (G) embryos. Abbreviations: drg: dorsal root ganglion; mt: motor neuron; nt: neural tube; SC: spinal cord; FB: forebrain; HB: hindbrain. Asterisk and arrowheads in H mark the swollen pericardial sac and kinked neural tube, respectively. Scale bars: 200um
