One day after President Obama negated George Bush's ban on stem cell experimentation, scientists announced that an effective stem cell treatment for strokes has taken a significant step forward. Scientists revealed how they have replaced stroke-damaged brain tissue in rats.
The team of scientists is funded by the Biotechnology and Biological Sciences Research Council (BBSRC) and led by Dr Mike Modo of the Institute of Psychiatry, King's College London. The work, carried out at the Institute of Psychiatry and University of Nottingham, shows that by inserting tiny scaffolding with stem cells attached, it is possible to fill a hole left by stroke damage with brand new brain tissue within 7 days. The work is published in Biomaterials on March 9.
Using individual particles of a biodegradable polymer called PLGA that have been loaded with neural stem cells, the team of scientists have filled stroke cavities with stem cells on a ready-made support structure.
Wow! The next 8 years ought to bring more and more of these victories as scientists here in America are able to begin anew their experiments, unfettered by political ideology. The British scientists had no such restrictions. Parkinson's and diabetes patients now have real hope that cures for their disorders will be discovered.
