And while there are still a number of hurdles to clear before this advance can be applied to humans, in the clinical setting this latest step, some say, shows promise of eventual human therapies.
Researchers from Harvard and Columbia Universities used skin cells from two patients with Amyotrophic Lateral Sclerosis (ALS), also known as Lou Gehrig's disease, to create stem cells and then reprogrammed them to morph into replacement motor neurons.
"It opens doors to making patient-specific stem cell lines," said Dr. Kevin Eggan, principle faculty member at the Harvard Stem Cell Institute and lead author of a study that was released today in the journal Science. "You can use these cells to make the actual cell type for that person's disease."
