Mouse Ventral Body Wall Development
The omphalocele, pubic diastasis, loss of pubic bones and polydactyly in Gli3Xt; Alx4Lst; Shh combinatorial mutants.
The lateral view of the embryonic ventral body wall (A–D, E, H) and frontal view of the pelvic girdle (A'–D', F, I). Gli3Xt/Xt embryos (B), Gli3Xt/Xt; Alx4Lst/+ embryos (C) and Gli3Xt/Xt; Alx4Lst/Lst embryos (D) showed a graded extent of omphaloceles by the introduction of additional Alx4Lst alleles into the Gli3Xt/Xt background (B–D; white arrows). The dorsal parts of the genital tubercle were hypoplastic in Gli3Xt/Xt; Alx4Lst/+ and Gli3Xt/Xt; Alx4Lst/Lst embryos (C, D; red arrowheads).
The pubic symphysis of wild-type embryo was already formed at E18.5 (A'; asterisk). Pubic diastasis also became evident by the introduction of Alx4Lst mutation (B'–D'). Gli3Xt/Xt; Alx4Lst/+ and Gli3Xt/Xt; Alx4Lst/Lst embryos showed partial loss of pubic bone components (C', D'; yellow arrowheads). Black arrows indicate the unclosed pelvis. Gli3Xt/+; Alx4Lst/Lst embryos showed omphalocele (E; red arrow), severe polydactyly (G), pubic diastasis and loss of pubic bones (F). Black arrows show the unclosed pelvis. Gli3Xt/+; Alx4Lst/Lst; Shh+/− embryos did not show omphalocele phenotypes (H). The pubic symphysis was formed but pubic bones were lost (I; asterisk). Polydactyly was still observed in Gli3Xt/+; Alx4Lst/Lst; Shh+/− embryos (J). Black arrowheads indicate extra digits.
