摘要: A method of reconstituting an animal embryo involves transferring the nucleus from a quiescent donor cell into a suitable recipient cell. The donor cell is quiescent, in that it is caused to exit from the growth and division cycle at G1 and to arrest in the G0 state. Nuclear transfer may take place by cell fusion. The reconstituted embryo may then give rise to one or more animals. The invention is useful in the production of transgenic animals as well as non-transgenics of high genetic merit.

摘要: PROBLEM TO BE SOLVED: To provide a method for reconstituting an animal embryo useful for producing a transgenic animal and a non-transgenic animal having a high genetic value. SOLUTION: In this method, a nucleus derived from a donor cell in a quiescent state is transferred into a suitable recipient cell. The donor cell exists in the quiescent state, from a viewpoint that the cell exits from a growth and division cycle on a G1 stage and remains in a G0 state. Nuclear transfer is conducted by cell fusion. Further, one or more animals are produced from the embryo thus reconstituted. COPYRIGHT: (C)2006,JPO&NCIPI

摘要: PROBLEM TO BE SOLVED: To develop a method of reconstituting an animal embryo, concerning animal production of genetically selected and/or modified animals and the like and to cells useful for production of the animals. SOLUTION: The method involves transferring a diploid nucleus into an oocyte which is arrested in the metaphase of the second meiotic division. The oocyte is not activated at the time of transfer, so that the donor nucleus is kept exposed to the recipient cytoplasm for a period of time. The diploid nucleus can be obtained from a cell in either the G0 or G1 phase of the cell cycle at the time of transfer. Subsequently, the reconstituted embryo is activated. Correct ploidy is maintained during activation, for example, by incubating the reconstituted embryo in the presence of a microtubule inhibitor such as nocodazole. The reconstituted embryo may then give rise to one or more live animal births. The method is useful in the production of transgenic animals as well as non-transgenics of high genetic merit.
