Mouse lines carrying:
Sall4^tm1Tre mutation (0 available); any Sall4 mutation (144 available)

♀	phenotype observed in females
♂	phenotype observed in males
N	normal phenotype

mortality/aging

embryonic lethality between implantation and somite formation, complete penetrance ( J:115635 )

• no embryos are found in vivo at E5.5; empty implantation sites are regularly found

• no ICM-derived embryonic structures are recognizable in implantation sites where homozygous E3.5 embryos were transplanted into pseudopregnant females

embryo

abnormal embryonic tissue morphology ( J:115635 )

• few mitotic cells are detected in mutant explants after 5 days of culture

abnormal inner cell mass morphology ( J:115635 )

• ICM of embryos cultured in ES cell medium do not expand significantly compared to wild-type and heterozygous embryos

• after 5 days of culture, extraembryonic cell marker H19 is detected in homozygous explants, but not in controls; a significant portion of cells are positive for Cdx2, but this is not seen in control explants

• trophoblast giant cells are observed when ICM from E3.75 heterozygous blastocysts are cultured, but not in heterozygous ICMs

embryo

absent trophoblast giant cells ( J:115635 )

• no trophoblast giant cells are observed when ICM from E3.75 heterozygous blastocysts are cultured

• when cultured, an epithelial-like cell type is obtained, but not in cultured homozygous blastocysts
