<<...Unlike human embryonic stem cells, stem cells derived from fetal tissue
are not capable of growing in culture indefinitely. But because neural fetal
stem cells have been available to science for a much longer period than cells
derived from embryos, their capabilities are better known to scientists and
they may reach the clinic as therapies for disorders like Parkinson's and
amyotrophic lateral sclerosis (ALS) much sooner.
In culture, the cells can be coaxed into becoming "neurospheres," aggregates
of precursor brain cells that, when implanted, can migrate to different parts
of the brain, integrate themselves and develop into many of the different
types of specialized cells that make up the brain.
"These cells are the basis for future therapies. These are the cells we want
to transplant," said Clive Svendsen, senior author of the Journal of
Neurochemistry paper and a leading authority on neural stem cells....>>
