Outline of Final Research Achievements

In this study, we examined whether pre-implantation stage embryos in mammals could be freeze-dried like sperm and somatic cells. When mouse blastocysts were freeze-dried, trehalose supplemented medium for freeze-drying and isotonic solution for rehydration were effective for their blastocoele recovery. For porcine blastocysts, no blastocysts recovered their blastocoele after rehydration in any approach.
