Information from provider
Provider | Claude Szpirer |
Provider affiliation | ULB-IBMM |
Genetic information | Targeted mutation obtained with a replacement vector that included flanking loxP sites. The mutation was generated using a mouse line expressing Cre in early development (PGK-Cre), resulting in mice lacking the entire Sp6 gene ubiquitously. See the publication mentioned below. |
Phenotypic information | The Sp6 KO mice are nude, lack functional teeth and present limb and lung malformations. They die within the first 5 weeks after birth, most likely as a result of the absence of a functional dentition. Apoptosis misregulation was found in some of the affected organs. |
Breeding history | The mutation was backcrossed for 10 generations on the 2 genetic backgrounds CD1 and C57BL/6. The two lines are bred in parallel. C57BL/6: fertility quite low. |
