| Outline of Final Research Achievements |
In order to produce monozygous Japanese monkeys as animal models for Cognitive Neuroscience, we examined and improved associated embryological engineering techniques. ① It was revealed that it was effective to make the dose of the hormone half of the known report to raise efficiency of the egg collection. ② TEST Yolk Buffer was suitable for the cryopreservation of the sperm. After melting, sperm was treated by the BO solution with 1mM Caffeine and 1mM dbcAMP. Such sperm could use n‐vitro fertilization. ③ Although an egg fertilized in vitro or splitter fertilized eggs were transplanted to female Japanese macaques, we were not able to confirm the pregnancy.
