Stem Cells Pulled From Cloned Embryos
Scientists have finally been able to recover stem cells from cloned human embryos, a longtime goal that could now lead to the treatment of many different diseases. Experts believe that scientists have reached a milestone with such a discovery, but they are in search of simpler recovery methods that could be more useful. Stem cells have the ability to turn themselves into any cell of the body. Scientists are interested in using stem cells in order to treat diseases such as Parkinson’s disorder or diabetes. Parkinson’s would be treated by transplanting brain tissue, but as with every transplant, there is the risk of rejection. To overcome rejection, researchers suggested that creating stem cells from patient DNA through a process called therapeutic cloning may reduce the risk. When DNA is taken from a patient and inserted into a human egg and is then allowed to grow into an early embryo, the stem cells yielded would be a virtual genetic match. If the stem cells are a genetic match, then the tissues created from them should not be rejected. Scientists have been trying to obtain stem cells from cloned human embryos for almost a decade, but have failed due to the embryos stopping to develop before producing the cells. Researchers are very excited about these findings as they could provide many cures to potential fatal diseases.
