Representation of different types of therapeutic cloning: - Removal of cells from a blastocyst cultured in the laboratory giving differentiated cells grafted onto a patient. - Collection of the genetic code of a woman combined with the envelope of an oocyte of another woman, cultured up to the blastocyst stage. The cells give rise to differentiated cells grafted onto the woman from whom the genetic code has been taken. - Same technique as above but with the envelope of a cow's oocyte.
