Cell scientists slow degeneration in motor neurone mice

TOKYO - Japanese stemcell scientists have succeeded in slowing the deterioration of mice with motor neurone disease, possibly paving the way for eventual human treatment, according to a new paper.

A team of researchers from the Kyoto University and Keio University transplanted specially created cells into mice with amyotrophic lateral sclerosis (ALS), also called Lou Gehrig's, or motor neurone disease.
The progress of the creatures' neurological degeneration was slowed by almost eight per cent, according to the paper, which was published Thursday in the scholarly journal Stem Cell Reports.
ALS is a disorder of motor neurones -- nerves that control movement -- leading to the loss of the ability to control muscles and their eventual atrophy.
While it frequently has no effect on cognitive function, it progresses to affect most of the muscles in the body, including those used to eat and breathe.
British theoretical physicist Stephen Hawking has been almost completely paralysed by the condition.
In their study, the Japanese team used human "iPS" -- induced pluripotent stem cells, building-block cells akin to those found in embryos, which have the potential to turn into any cell in the body.
From the iPS cells they created special progenitor cells and transplanted them into the lumbar spinal cord of ALS mice.
