Human embryos

The purposes: Identify the morphological characteristics of day 3 and day 5 embryos cultured in vitro; assess the morphological correlations of day 3 and day 5 embryos and initially evaluated results of sequential embryo selection in culturing the day 3 and day 5 embryos.

The tissue-specific transcription factorsHNF1aandHNF1b are closely related homeodomain proteins conserved in vertebrate evolution. Heterozygous mutations in human HNF1b 1 but not inHNF1agenes are associated with kidney malformations. Overexpression of HNF1b in Xenopus embryos leads to defective pronephros development, while HNF1ahas no effect. We have defined the regions respon-sible for this functional difference between HNF1band HNF1ain transfected HeLa cells as well as in injected Xenopusembryos. ...

Elevated cell death in human preimplantation embryos is one of the cellu-lar events compromising pregnancy rates after assisted reproductive tech-nology treatments. We therefore explored the molecular pathways regulating cell death at the blastocyst stage in human embryos cultured in vitro. Owing to limited availability of human embryos, these pathways were further characterized in mouse blastocysts.
