Stem Cell Therapy


The same technique as cloning is used in stem cell therapy.  Some call it therapeutic cloning versus reproductive cloning.  Here, rather than duplicating a whole human being, a patient's diseased cells or organ are replaced by stem cells from a donor — cells that are programmed to develop into, say, bone marrow or brain cells. 

Some of the controversies surrounding stem cell therapy are:
 Since it's the same technique — will therapeutic cloning lead, eventually, to reproductive cloning?
 Is embryonic stem cell therapy ethical?
     (Prohibited under Pres. G. W.   Bush)
 Is it ethical to create a savior child — a genetically identical child who can donate stem cells to a sibling?
