Figure 3. Evc2 homozygous mutant mice show dwarfism.
(a–b) LacZ staining showing Evc2 expression pattern of growth plates of indicated bones from wild type (a) and heterozygous Evc2 (b) mice. (c) Dorsal view of an Evc2ex12/ex12 mutant mouse with littermate controls at the newborn stage. (d, e) Dorsal view of Evc2ex12/ex12 mice with littermate controls at 1 week (d) and 6 weeks (e) after birth. (f) Side view of skeleton preparation of Evc2 ex12/ex12 and a littermate control at 4 weeks after birth. (g) Body weight gains of male and female Evc2 ex12/ex12 (red) and littermate controls (blue) were shown respectively (*, p<0.05, **, p<0.01). (h) Skeletal preparation of limbs from E18.5 Evc2 ex12/ex12 and littermate control indicated shorter forelimb and hindlimb in the Evc2 mutant. (i) Quantification of the length of indicated appendicular bone in (h) (n=10, *, p<10−10). Hu, humerus; Ul, ulna; Ra, radius; Fe, femur; Ti, tibia. (j) Skeleton preparation of limbs from E18.5 Evc2dE/dE embryos and littermate controls indicated shorter forelimb and hindlimb in the Evc2 mutant. (k) Quantification of the length of indicated appendicular bone in (j) (n=10, *, p<10−10). Scale Bar: 200 um for a and b, 1 mm for h and j.
