One molecule makes nerve cells grow longer. Another one makes them grow branches. These new experimental manipulations have taken researchers a step closer to understanding how nerve cells are repaired at their farthest reaches after injury. The research was recently published in the Journal of Neuroscience.
“If you injure a peripheral nerve, it will spontaneously regenerate, but it goes very slowly. We’re trying to speed that up,” said Dr. Jeffery Twiss, a professor and head of the biology department at Drexel University in the College of Arts and Sciences, who was senior author of the paper.
