Stem Cells and Amyotrophic Lateral Sclerosis

The generation of pluripotent stem cells from an individual patient would enable the large-scale production of the cell-types affected by that patient’s disease. These cells could in turn be used for disease modeling, drug discovery, and eventually autologous cell-replacement therapies. Although recent studies have demonstrated the reprogramming of human fibroblasts to a pluripotent state, it remains unclear whether these induced pluripotent stem (iPS) cells can be produced directly from elderly patients with chronic disease. We have generated iPS cells from an 82-year-old woman diagnosed with a familial form of amyotrophic lateral sclerosis (ALS). These patient-specific iPS cells possess properties of embryonic stem cells and were successfully directed to differentiate into motor neurons, the cell type destroyed in ALS.
