In mice, basic reproductive technologies, such as oocyte/sperm collection, embryo production, micromanipulation, and embryo transfer, have been established. With these technologies, production of transgenic mice has become routine. The cynomolgus monkey, which is one of the laboratory animals closest to human beings, has been used to obtain vaccine approval and for medical research. Therefore, production of transgenic animals in the monkey is a very significant subject. We describe herein the current state of related studies in addition to current findings regarding reproductive technologies.
