Conditional mutation of fibroblast growth factor receptors 1 and 2 results in an omphalocele in mice associated with disruptions in ventral body wall muscle formation.

Abstract excerpt

BACKGROUND/PURPOSE: We observed that fibroblast growth factor receptors 1 and 2 (Fgfr1, Fgfr2) are expressed during abdominal wall development in mice and hypothesized that conditional mutation of these genes would result in abdominal wall defects. METHODS: Section in situ hybridizations were performed for Fgfr1 and Fgfr2 on wild-type embryos at embryonic day (E) 11.5 and E13.5. Conditional mutation of Fgfr1and...
