Microscopic fibers string spinal cord back together


<p>With plans just approved for the first trial to treat spinal cord injuries in humans with embryonic stem cells, a team of Northwestern scientists is tackling the problem from a different angle: through microscopic messenger molecules that can tell the disconnected nerve cells to re-grow.</p> <p>The molecules are called nanofibers, and scientists at Northwestern’s Institute for BioNanotechnology in Medicine are…</p>
