Tmem107–/– mutants display
multiple gross morphological defects in craniofacial regions. E12.5,
Tmem107–/– embryos
(I, I′, J) exhibit
exencephaly and altered morphology of the rostrum in comparison to
wild-type (wt) animals (A, A′,
B). At E13.5, Tmem107–/– mutants display cleft lip and palate
(K′, L), in comparison to wt controls
(C, C′, D). At E14.5, Tmem107–/– embryos display shorter
snouts (M) together with cleft lip and palate
(N) in contrast to wt animals (E,
F). At E15.5, Tmem107–/– mutants show altered morphology
of snout, together with cleft lip and palate (O′,
P), compared to wt mice (G,
G′, H). At all stages examined, Tmem107–/– embryos displayed
reduced or absent eyes. Scale bar = 1 mm.
