Therapeutic cloning 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
