Fig 4. Gross appearance of and growth curves for Δ11 mutant rats.
(A) and (B) Gross appearance of male WT rat and rat with a homozygous Δ11 mutation at two weeks (A) and 14 weeks (B) of age. Black scale bar in each picture denotes 10 mm. (C) Growth curves for Δ11 mutant rats. Upper panels show naso-anal lengths of male (left) and female (right) rats and lower panels exhibit body weight. n = 6, 15, and 10 for male WT, heterozygous Δ11, and homozygous Δ11 rats, respectively; n = 8, 14, and 5 for female WT, heterozygous Δ11, and homozygous Δ11 rats, respectively. *, P < 0.01 vs WT, §, P < 0.01 vs WT, and ¶, P < 0.05 vs WT.
