Fig. 2.
Length of radius and ulna and bone deformation during embryonic development. Long bones from newborn (P0) mice were dissected, stained with Alizarin Red and Alcian Blue and the bone lengths were measured (A, C). Data in (A) are means ± SEM from 4 littermates of each genotype; *: P < 0.05 compared to WT. Forelimbs were dissected free from soft tissues. E13.5-E15.5 forelimbs were stained with Alcian Blue only whereas E17.5 forelimbs were stained with both Alizarin Red and Alcian Blue.
