regenerating axons

How to regenerate axons to recover from spinal-cord injury
July 17, 2015

HKUST researchers cut mouse corticospinal tract axons (labeled red). A year later, they deleted the Pten gene in the experimental group (bottom) but not the control group. The Pten gene removal resulted in axon regrowth in seven months, unlike the control group (top). (credit: Kaimeng Du et al./The Journal of Neuroscience) Researchers at the Hong Kong University of Science and Technology (HKUST) have found a way to help patients recover from chronic spinal cord injury (SCI) by stimulating the growth of axons. Chronic SCI prevents a large number of injured axons from crossing a lesion, particularly in the corticospinal tract (CST). Patients inflicted with SCI often … more…
