| Genetic information | The mutation has been obtained by homologous recombination to introduce the amino acid substitution F78A in the Cripto (Tdgf1) gene. RI ES cells were transfected with a targeting vector that was derived from pFlox vector (Chen et al., 1998) and selected in G-418. The presence of the point mutation in the targeted cells was verified by PCR amplification and sequence analysis. Selected ES cells lines were used to generate germline chimeric mice that were subsequently bred to C57BL/6 females (Charles River Laboratories). F1 Cripto-F78Aneo heterozygotes were crossed with a Pgk-cre recombinase deleter strain to obtain the Cripto-F78A strain. For a more detailed description of the targeting vector, see D'Andrea et al. 2008, J Cell Biol. |
| Phenotypic information | Embryonic lethal at 10.5 dpc. Cripto-F78A/F78A embryos establish an A-P axis and initiate germ layer formation and gastrulation movements. The heterozygous mutants do not show any apparent phenotype, they are healthy and fertile. |
| Breeding history | Mice heterozygous for the Cripto-F78A allele are backcrossed to an inbred C57BL/6 strain. |
