(Reprinted at CAMR). "A University of Wisconsin-Madison researcher said he would ask federal regulators Friday to approve the first clinical trial injecting special stem cells into the spinal cords of people with the degenerative nerve ailment called Lou Gehrig's disease." It is good to see more promising signs of progress towards therapies for neurodegenerative conditions; this and similar work forms a platform on which to build a greater understanding of age-related damage to the brain. Unlike other organs, we can't just replace the brain with fresh tissue in a worst case scenario for healthy life extension - so we had better get very good at understanding, repairing and preventing the myriad ways in which this complex machine fails with age.
