Injectable gel could heal brain injuries - Telegraph

   "The material, containing a cocktail of synthetic and natural
    chemicals, spurs on the growth of neural stem cells which in turn
    repair damaged nerves. After promising studies on rats
    scientists in the US say the treatment could be ready for patient
    trials in as little as three years"

   "It is hoped the biogel will be useful in the treatment of wounded
    soldiers with head injuries. Modern protective clothing and
    equipment has led to larger numbers of combat soldiers suffering
    serious injuries who previously would have died"

   "''These results that we are seeing in adult lab rats are the
    first of its kind and show a sustained functional recovery in the
    animal model of TBI (traumatic brain injury). It also represents
    one of very few in the traumatic brain injury field that
    attempts structural repair of the lesion cavity using a tissue-
    engineering approach"

   "Current strategies for tackling traumatic brain injury include
    hypothermia - or cooling - and protecting surviving nerve cells
    with chemical agents. However, their success is limited. The new
    procedure involves injecting the biogel into the wound site to
    direct the response of neural stem cells. Stem cells are immature
    ''mother'' cells that can generate different types of tissue.
    Those in the brain produce nerve cells. Chemicals in the biogel
    help the neural stem cells to regenerate normal brain tissue at
    the site of damage"
