Somatic Cell Nuclear Transfer (SCNT) and Therapeutic Cloning for Stem Cells involves taking the nucleus of an egg cell, replacing it with the material from the nucleus of a "somatic cell" (a skin, heart, nerve or any other non-germ cell), and stimulating this cell to begin dividing. This egg cell is never fertilized by sperm, and the genetic material within the cell is virtually identical to the genetic material extracted from the skin or other cell.
