| Caption | Mia3tm1Lex/Mia3tm1Lex (Mia3-/-) embryos are dwarfed, edemic, and fail to form a mineralized skeleton. (A and B) Mutant embryos display a shortening of the snout and limbs at 16.5 days post coitum (dpc). (C and D) Mutant embryos are significantly dwarfed at 18.5 dpc. (E and F) Alizarin red-positive skeletal mineralization initiates within the intramembranous bone of the jaw and endochondral bones of the clavicles of 13.5-dpc wild-type (WT) embryos (arrows) but is absent from the Alcian blue-positive cartilage anlagen of mutants. (G and H) Mineralization is advanced in nearly all axial and appendicular elements in 15.5-dpc control embryos but is profoundly delayed in the null skeleton. (I-L) Calcified matrix is apparent in the bones of 18.5-dpc knockout animals (I and J), but micro-CT (n = 3) maximum intensity projections highlight complete absence of the mature ossified skeleton (K and L). Bars, 1 mm. | ||||||
