Phenotype Image Detail

Caption Staining of calcified tissue in neonatal mice with alizarin red S. From left to right are wild-type mouse (A), Tg(Col2a1-PTHLH)2Ecw/0 mouse (B) Pthlhtm1Hmk/Pthlhtm1Hmk mouse (C) and Pthlhtm1Hmk/Pthlhtm1Hmk Tg(Col2a1-PTHLH)2Ecw/0 mouse (D). The Pthlhtm1Hmk/Pthlhtm1Hmk mice display inappropriate ossification of the costal cartilage and along the length of the sternum. These abnormalities appear to be largely corrected in the Pthlhtm1Hmk/Pthlhtm1Hmk Tg(Col2a1-PTHLH)2Ecw/0 mice (D), in which ossification is confined to the sternebrae and does not extend to the costal cartilage. A magnified view of the cranium (H) shows substantial correction of the accelerated mineralization of the endochondral bones of the cranial base seen in the knockout (G); s, supraoccipital; b, basioccipital; e, exoccipital; t, tympanic ring. The tips of the emerging mandibular incisors can be discerned in both the normal (E) and transgenic (F) animals, but not in the knockout (G) or rescued-knockout (H) mice.
