Mexican Walking Fish may hold key to helping paralysed people walk again

The axolotl, or Mexican salamander has the astonishing ability to regenerate limbs and even spinal cord if it has been injured.

But now a new study by the University of Minnesota in the US has discovered how the animals achieve the feat.

When an axolotl suffers a spinal cord injury, nearby cells called glial cells begin proliferating rapidly, repositioning themselves to rebuild the connections between nerves and reconnect the injured spinal cord.

By contrast, when a human suffers a spinal cord injury, the glial cells form scar tissue, which blocks nerves from ever reconnecting with each other.
