Phenotype Image Detail
Image
Caption (A-D) E17.5 wild-type (+/+) (A) and Ptk7chz/Ptk7chz (chz/chz) embryos (B-D) in lateral (A-C) and dorsal view (D). Mutant embryos demonstrate the severe neural tube defect of craniorachischisis, where the neural tube is open from the midbrain/hindbrain boundary throughout the hindbrain and spinal cord, and the neural tissue is splayed on either side of the dorsal midline (D). Some mutants demonstrate failure to form closed eyelids (C) and a defect in ventral body wall development (likely omphalocele) with protrusion of the liver and guts (C). (E-L) Skeletal preparations of E17.5 wild-type (E, G, I) and mutant (F, H, J-L) fetuses stained with alcian blue for cartilage and alizarin red for bone. Dorsal views (E, F) demonstrate shortened and skewed body axis in mutants, with splayed vertebrae. Lateral views (G, H) reveal abnormal rib morphology, with fusions and bifurcations. Mutant limbs sometimes exhibit polydactyly with an extra digit postaxially (J, arrow) or preaxially (K, L arrows).
