Cell reprogramming
First Claim
1. A method for reprogramming differentiated or partially differentiated cells to a less differentiated or dedifferentiated state, which method includes providing a karyoplast of a differentiated or partially differentiated cell;
- and a source of multinucleate, aneuploid, euploid or polyploid multipotent or pluripotent cells, or morula or early embryos, or derivatives thereof; and
placing the karyoplast in intimate contact with the multipotent or pluripotent cells, or morula or early embryos or derivatives thereof under conditions sufficient to permit at least partial reprogramming of the cells.

22. A method for reprogramming differentiated or partially differentiated cells to a less differentiated, or dedifferential state, by formation of a cell hybrid, which method includes
providing: -
a source of karyoplasts of differentiated or partially differentiated cells;
a source of multipotent or pluripotent cells, morula or early embryos or derivatives thereof;
placing the karyoplasts in intimate contact with the multipotent or pluripotent cells;
subjecting the cells to a cell fusion step to form a cell hybrid;
subsequently removing from said reprogrammed cells, the multipotent or pluripotent cell nuclei; and
culturing the reprogrammed cells to permit proliferation thereof. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30)

31. A method for reprogramming differentiated or partially differentiated cells to a less differentiated or dedifferentiated state, which method includes
providing a source of cytoplasm from a multinucleate, aneuploid, euploid or polypoid multipotent or pluripotent cell; -
a karyoplast derived from a partially or terminally differentiated cell differing from the cytoplasm source;
a suitable culture medium combining the cytoplasm source and karyoplast to form a reconstructed cell; and
maintaining the reconstructed cell in the culture medium for a time sufficient to permit at least partial reprogramming of the karyoplast in the combined cell. - View Dependent Claims (32, 33, 34, 35, 36, 37)
