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?
