Postnatal growth kinetics of WT and Csgalnact1−/− mice. A, WT (+/+) and Csgalnact1−/− (−/−) male littermates at 24 weeks of age. B, filled circles, WT (male, n = 7; female, n = 6); open circles, Csgalnact1 −/− mice (male, n = 6; female, n = 7). Csgalnact1−/− mice were significantly smaller than WT mice (p < 0.01, two-way repeated-measures ANOVA).
