Phenotype Image Detail

Caption

Znhit2^em1(IMPC)J/Znhit2^em1(IMPC)J mutants are able to form blastocysts but cannot expand further or hatch out in vitro. Many mutant embryos become collapsed or dead after 24hrs culture. Arrowheads point to scattered DAPI signal, indicating fragmented DNA. Znhit2 mutant embryos exhibit a complete absence of SOX2+ and SOX17+ cells, while NANOG doesnt turn off properly in trophectoderm. RT-PCR results showed the robust expression of Znhit2 and Sox2 in wild-type and heterozygous blastocysts, but not in mutant embryos. BL Mut, mutant blastocyst, CL Mut, collapsed mutant.
