Figure 1. Neither ERRγ ablation nor haploinsufficiency has a detectable effect on embryonic bone development and growth.

(A) Whole mount alizarin red/alcian blue staining revealed no observable morphological differences in newborn mouse ERRγ +/+, ERRγ +/− and ERRγ −/− skeletons (upper panel) or in the craniofacial regions (lower panel). (B) Skeletal elements that make up the mouse forelimb of each genotype were measured and found to have no significant differences. (N = 5 ERRγ +/+; N = 3 ERRγ −/−). Values are expressed as mean ± SD.
