Transverse growth of the mouse craniofacial skeleton. (A) Diagram of mouse skull at ventral view with landmarks and parameters used for transverse dimension measurements. (B) Growth curves showing changes in transverse dimension with age (landmarks and labels were described in Figure 1 and Table 1), including 4 parameters in facial region (upper) and 3 parameters in cranial region (lower). ^*Represents significant change between indicated data point and immediate earlier time point, and red arrows indicate significant changes between all the neighboring time points before that time point (Tukey's multiple comparison test, p < 0.05). NS indicates that there was no statistical significance among the data points.
