Summary:
Researchers have identified a stage during dopamine neuron differentiation that may be an ideal time to collect human embryonic stem cells for transplantation to treat Parkinson's disease, according to data presented at Neuroscience 2008, the 38th annual meeting of the Society for Neuroscience. Lorraine Iacovitti, Ph.D., professor and interim director of the Farber Institute for Neurosciences of Thomas Jefferson University, and her research team found that neural progenitor cells that express the gene Lmx1a are committed to the midbrain dopamine neuron lineage, but still retain proliferative capacity. Because of these characteristics, the stage at which Lmx1a is expressed may be ideal for transplantation.
