Transplanted astrocytes repair spinal cord damage in rat

A couple of weeks ago I discussed the launch of two clinical trials of brain machine interfaces designed to allow quadriplegic patients to control a newly designed prosthetic limb, during which I mentioned that scientists are also studying techniques that attempt to repair damage to spinal cords using stem cells.  Several approaches have already shown … Continue reading Transplanted astrocytes repair spinal cord damage in rat

Of mice and mTOR: Can damaged spinal cords be taught to repair themselves?

There's an interesting story on the BBC website about new research on nerve cell regeneration after spinal cord damage in mice, work undertaken by a team led by Dr. Zhigang He of the F.M. Kirby Neurobiology Center at Children's Hospital Boston. Those of you who follow developments on the field of spinal cord repair may … Continue reading Of mice and mTOR: Can damaged spinal cords be taught to repair themselves?

Working toward a cure for paralysis

We have been pleasantly surprised by the magnitude of the positive responses received from our recent publication in Nature Neuroscience regarding the demonstration of several interventions which resulted in the recovery of well controlled locomotion after a complete spinal cord injury. It has been characterized as a major breakthrough in facilitating the level of recovery … Continue reading Working toward a cure for paralysis

A new era for embryonic stem cells

As the new president takes office and the scientific community eagerly awaits the announcement of the reversal of the ban on federal funding of most research involving human embryonic stem cells (hESC's), there's news that the FDA has approved the first ever trial of a treatment based on hESC's for severe spinal cord injury. This … Continue reading A new era for embryonic stem cells
