"Therapeutic" cloning involves, basically, the same procedures as those employed to clone for reproductive ("making a baby") purposes. A cell is taken from an adult, its nucleus is removed and then placed into an egg cell from which the nucleus has been removed. This technique is called, in scientific jargon, "somatic cell nuclear transfer." Using various chemical and/or electric measures, this egg cell with its new nucleus is stimulated to divide and give rise to either a whole organism (e.g., Dolly the sheep) or used to produce a specific line of cells (so-called therapeutic cloning to make new hearts, kidneys, etc.).
