Reporting in the journal Cell Stem Cell, scientists say that stem cells turned into motor nerves function nearly identically to fetal motor nerves: the kind now used to treat some patients with Parkinson’s disease. That could mean that the stem cells may become an important source of new nerves to replace the ones damaged in diseases like Parkinson’s.

In Parkinson’s, motor nerves that normally produce dopamine, which is critical for regulating muscle movements and controlling dexterity, are damaged, and dopamine levels drop dramatically. The researchers, led by Malin Parmar, an associate professor of regenerative neurobiology at Lund University, took human embryonic stem cells extracted from excess IVF embryos and treated them to develop into motor neurons. They transplanted these neurons into the brains of rats bred to develop Parkinson’s and found that the lab-made cells brought dopamine levels in these animals back to normal levels in five months. The…
