One way an induced pluripotent stem cell can be formed is through a somatic cell nuclear transfer. The nuclear transfer involves a somatic donor cell and an unfertilized, enucleated oocyte. The nuclear DNA from the somatic cell is then transplanted into the oocyte. It is then stimulated by an increase in the intracellular-free calcium concentration from an electrical pulse or by chemical agents. The cell is then cultured and eventually to a foster mother. The embryo contains the genetic information of the somatic cell and the embryo itself.
