Patent number: 8222385Abstract: In order to examine whether or not a germ cell derived from a donor fish, which has been transplanted into a recipient fish of a different species by a surrogate fish technique, grows or matures in the gonad of the recipient fish, it is necessary to use, as an indicator, a trait that is specifically expressed in the germ cell and can be used to distinguish the recipient fish from the donor fish. Vasa gene, which is a germ cell-specific gene, is specific to a primordial germ cell and a spermatogonium/an oogonium, and it is not expressed in a somatic cell. In the present invention, the Vasa gene sequences of a tuna, a chub mackerel, a spotted mackerel, an eastern little tuna, and a drumfish are determined, and the expression of such gene is used as a marker for a germ cell. In addition, according to the present invention, it is possible to specifically detect only a tuna Vasa gene in Vasa gene sequences that are highly conserved in fishes, without sequencing.Type: GrantFiled: March 26, 2008Date of Patent: July 17, 2012Assignees: National University Corporation Tokyo University of Marine Science Technology, Nippon Suisan Kaisha, Ltd.Inventors: Goro Yoshizaki, Yutaka Takeuchi, Kazue Nagasawa, Kentaro Higuchi, Tetsuro Morita, Naoki Kabeya

Publication number: 20110244485Abstract: An object of the present invention is to provide a means for distinguishing between a germ cell derived from a donor (tuna) and a germ cell derived from a recipient in a method for inducing differentiation of a tuna germ cell, wherein a primordial germ cell derived from the tuna is transplanted into an early embryo of the heterologous recipient fish. The present inventors compared a Vasa amino acid sequence of bluefin tuna with those of other fish (black skipjack, skipjack, chub mackerel, blue mackerel, round frigate mackerel and frigate mackerel), identified amino acid sequence regions specific to bluefin tuna, and, by using the amino acid sequences specific to bluefin tuna as antigens, successfully produced monoclonal antibodies specifically recognizing primordial germ cells, spermatogonia, oogonia or oocytes derived from bluefin tuna, thus accomplishing the present invention.Type: ApplicationFiled: September 25, 2009Publication date: October 6, 2011Applicants: National University Corporation Tokyo University of Marine Science and Technology, Nippon Suisan Kaisha, Ltd.Inventors: Goro Yoshizaki, Yutaka Takeuchi, Misako Miwa, Naoki Kabeya
