LOS ANGELES (EMBARGOED UNTIL NOON EDT ON JUNE 28, 2012) Cedars-Sinai scientists have joined with expert colleagues around the globe in using stem cells to develop a laboratory model for Huntington's disease, allowing researchers for the first time to test directly on human cells potential treatments for this fatal, inherited disorder.
As explained in a paper published June 28 on the Cell Stem Cell website and scheduled for print in the journal's Aug. 3 issue, scientists at Cedars-Sinai's Regenerative Medicine Institute and the University of Wisconsin took skin cells from patients with Huntington's disease and reprogrammed them into powerful stem cells; these were then made into the nervous system cells affected by the disease. Seven laboratories around the world collaborated to demonstrate the cells had hallmarks of Huntington's.
"This Huntington's 'disease in a dish' will enable us for the first time to test therapies on human Huntington's disease neurons," said Clive Svendsen, PhD, director of the Cedars-Sinai Regenerative Medicine Institute and a senior author of the study. "In addition to increasing our understanding of this disorder and offering a new pathway to identifying treatments, this study is remarkable because of the extensive interactions between a large group of scientists focused on developing this model. It's a new way of doing trailblazing science."
The Huntington's Disease iPSC Consortium united some of the world's top scientists working on this disease. Cedars-Sinai researchers took skin cells from a several Huntington's patients, including a six-year-old with a severe juvenile form of the disease. They genetically reprogrammed these tissues into induced pluripotent stem cells, which can be made into any type of cell in the body. The cells lines were banked by scientists at Cedars-Sinai and scrutinized by all consortium members for differences that may have led to the disease. These cell lines are now a
