REGENERATION METHOD USING SOMATIC CELL NUCLEAR TRANSFER (SCNT) CELL AND BLASTOCYST COMPLEMENTATION
First Claim
1. A method for producing a target organ in a living body of a non-human first mammal having an abnormality associated with a lack of development of the target organ in a development stage, the target organ produced being derived from a second mammal that is an individual different from the non-human first mammal, the method comprising:
- a) preparing a somatic cell nuclear transfer cell (SCNT cell) derived from the second mammal;
b) transplanting the SCNT cell into a blastocyst of the non-human first mammal, to yield a chimeric embryo;
c) developing the chimeric embryo in a uterus of a non-human third mammal to obtain at least one offspring comprising the target organ; and
d) obtaining the target organ from the at least one offspring.

Abstract
We disclose that a target organ such as kidney can be regenerated by complementing a developmental deficiency leading to a lack of development of the target organ in a non-human first mammal by injecting a somatic cell nuclear transfer cell (SCNT cell) into a developed blastocyst of the non-human first mammal. We also disclose a method for producing a target organ, using an SCNT cell, in a living body of a non-human first mammal having an abnormality associated with a lack of development of the target organ in a development stage, the target organ produced being derived from a second mammal that is an individual different from the non-human first mammal.

10. A non-human first mammal having an abnormality associated with a lack of development of a target organ in a development stage, the mammal being produced by a method comprising:
- a) preparing an SCNT cell derived from a second mammal that is an individual different from the non-human first mammal;
b) transplanting the SCNT cell into a blastocyst of the non-human first mammal, to yield a chimeric embryo; and
c) developing the chimeric embryo in a uterus of a non-human third mammal to obtain at least one offspring comprising the target organ.

11. A kit for producing a target organ, the kit comprising:
- A) a non-human first mammal having an abnormality associated with a lack of development of the target organ in a development stage; and
B) an SCNT cell derived from a second mammal that is an individual different from the non-human first mammal.
- A) a non-human first mammal having an abnormality associated with a lack of development of the target organ in a development stage; and

12. A method for producing one or more of a target organ and a target body part, the method comprising:
-
providing a non-human animal which includes a deficiency-responsible gene coding for a factor which causes a deficiency of one or more of an organ and a body part and gives one or more of no possibility of survival and difficulty in survival if the factor functions, and in which the one or more of an organ and a body part is complemented by blastocyst complementation, the deficiency-responsible gene coding for a factor which causes a deficiency of the one or more of a target organ and a target body part; growing an ovum obtained from the non-human animal into a blastocyst; introducing a target somatic cell nuclear transfer cell (SCNT cell) into the blastocyst so as to produce a chimeric blastocyst, the target SCNT cell having a desired genome capable of complementing a deficiency caused by the deficiency-responsible gene; producing an individual from the chimeric blastocyst; and obtaining the one or more of a target organ and a target body part from the individual. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)

- A) a non-human animal which includes a gene coding for a factor which causes a deficiency of one or more of an organ and a body part and gives one or more of no possibility of survival and difficulty in survival if the factor functions, and in which the one or more of an organ and a body part is complemented by complement; and
B) an SCNT cell derived from a second mammal that is an individual different from the non-human animal. - View Dependent Claims (23)
