Phenotype Image Detail
Caption Panels A and B. Four week old littermates, +/+ wildtype (left) and Fgfr2tm4Lni/+ (right). The Fgfr2tm4Lni/+ skulls are rounded due to shortening of the rostrocaudal axis. Arrows indicate obliterated coronal and fusion of the lambdoid sutures. Arrowheads point to normal basioccipital-exoccipital-basisphenoid synchondroses in the wildtype (left) in contrast to the loss of function mutation in the precociously fused Fgfr2tm4Lni/+ mouse (right). Panel C. Histological coronal suture sections frontal and parietal bones at E16.5 and obliterated suture at P29 (arrows). Abbreviations: frontal (f); parietal (p). Scalebars, 200um.
