| Outline of Final Research Achievements |
It was demonstrated that commercially available human in-vitro fertilization medium had contained 500uM-1000uM octanoic acid, using mass spectrometric analysis. Using F1 and inbred mice in-vitro fertilized embryo, several effects were recognized in the medium containing 800 and 1200uM of OA ; 1) in vitro embryo development (up to blastocyst stage) were delayed and disturbed, 2) implantation rates were decreased and 3) body weight were decreased after 179days after birth. Gene expression analysis revealed that expression pattern were different in several genes, including imprinting genes.
