Summary:
A team of researchers -- led by Sang-Hun Lee, at Hanyang University, Republic of Korea, and Kwang-Soo Kim, at Harvard Medical School, Belmont, -- has now compared the ability of cells derived from different types of human stem cell to reverse disease in a rat model of Parkinson disease and identified a stem cell population that they believe could be clinically relevant.
The researchers found several problems with cells derived from virus-based human iPS cells that precluded their use in the Parkinson disease model but found that nerve cells derived from protein-based human iPS cells reversed disease when transplanted into the brain of rats modeling Parkinson disease. They therefore conclude that protein-based human iPS cells could be used in the treatment of individuals with Parkinson disease.
The study is published in the Journal of Clinical Investigation.
