Researchers at Keio University's medical school said they have succeeded in regenerating severed peripheral nerves in rats, potentially paving the way for more effective treatment of neurological disabilities associated with loss of sensory nerves through accidents or surgery.
Existing medical technology offers limited choices to mend peripheral nerves. One method is to transplant peripheral nerves from other parts of the body, but doctors say the scope of such transplants is limited.
The Keio research, led by lecturer Yasushi Nakao and professor Hideyuki Okano, essentially involves constructing a tiny artificial vein and growing nerve cells inside.
