Therapeutic cloning<span>generates personalized ES cells
o Uses the technique of nuclear transplantation to produce cultured ES cells
o The cell that has received the transplanted nucleus is allowed to undergo the earliest steps of development giving rise to a very early embryo consisting of about 200 cells
• Not transferred into the uterus of a foster mother but used as a source from which ES cells are derived
o Cells obtained are genetically identical to the original donor
• Can be grafted back into the adult from whom the donor tissue was taken without fear of immunological rejection</span>
