    Abstract: The invention provides a method for effecting the de-differentiation of a somatic cell by culturing the cell in the absence of growth factors, cytokines, or other differentiation-inducing agents, and introducing components of cytoplasm of plutipotent cells into the somatic cell and allowing the cell to de-differentiate. The method can be used with somatic cells of any type, from any species of animal. The pluripotent cells may be oocytes, blastomeres, inner cell mass cells, embryonic stem cells, embryonic germ cells, embryos consisting of one or more cells, embryoid body (embryoid) cells, morula-derived cells, teratoma (teratocarcinoma) cells, as well as multipotent partially differentiated embryonic stem cells taken from later in the embryonic development process. After being de-differentiated, the cell can be induced to re-differentiate into a different somatic cell type. A method for de-differentiating a somatic cell and inducing it to re-differentiate into a cell of neural lineage is disclosed.

    Abstract: Improved methods of cell therapy are provided using cells and tissues that are histocompatible with a human or non-human mammal transplant recipient. The cells and tissues for transplant produced by the present invention exhibit a youthful state and can be committed to specific cell lineages to better infiltrate and proliferate at a desired target, e.g., a tissue, or organ in need of cell replacement therapy. For providing cells and tissues for transplant to a non-human mammal, the cells and tissues can be isolated from a gastrulating embryo produced by same-species nuclear transfer. Histocompatible cells and tissues for transplant to a human can be isolated from a gastrulating embryo that (i) is genetically modified to be in capable of developing beyond and early stage, or (ii) is produced by cross-species nuclear transfer between a human nuclear donor cell and an enucleated recipient cell, e.g., an oocyte, of a non-human mammal, or (iii) is produced by androgenesis or gynogenesis, or from pluripotent stem cells generated from such an embryo. Methods for producing histocompatible cells and tissues for transplant to a human can also be used to produce such cells or tissues for transplant to non-human mammals. The present invention also provides model embryonic systems having defined genetic makeup that are useful for developing and testing methods for cell and tissue therapy, and for studying genetic imprinting, reprogramming, rejuvenation, and other biochemical, metabolic, and physiological phenomena associated with embryogenesis.

    Abstract: The invention is concerned with producing differentiated cells, tissues and organs from pluripotent and mutlipotent cells. The methods of the invention are particularly useful for producing differentiated cells from pluripotent cells wherein communication between the cells of more than one embryonic germ layer or more than one organ system are required for development along a specific cell lineage. The invention methods are effected by in vivo or in vitro culturing of embryonic and developing or developed allogeneic or xenogeneic cells.
