A study recently conducted at the Massachusetts Institute of Technology (MIT) showed for the first time that artificially created stem cells can be used to treat Parkinson’s disease. In another research project conducted at the Imperial College in London, scientists identified the source of nerve cells in the embryo. The findings of these research projects have led scientists to believe stem cells can be used in new therapies for Parkinson’s disease. Parkinson's disease (PD) is a degenerative neurological disorder that occurs when nerve cells (neurons) in an area of the brain that controls muscle movement die or become impaired. Currently,...
