Outline of Final Research Achievements

The aim of this study was to establish blastocyst production system from freeze-dried (FD) sperm and diploid cells in the bovine species. Results obtained were: (1) Incorporation of trehalose using alpha-hemolysin mutant did not inhibit DNA damage in FD granulosa cells. (2) Incidence of FD cake collapse was related with the glass transition temperature of the maximally freeze-concentrated phase (Tg'), and trehalose in FD buffer contributed to increase the Tg' and to inhibit the cake collapse. (3) ROCK inhibitor or alpha-tocopherol supplemented to recovery culture medium could rescue metaphase-II oocytes after vitrification and warming. (4) Morphologically normal blastocysts derived from both FD spermatozoa (via intracytoplasmic sperm injection) and FD fibroblasts (via somatic cell nuclear transplantation) were successfully produced in vitro.
