Using stem cells, researchers discern patterns to this puzzling disorder
Alzheimer's research is equal measure hope and frustration. Cord blood might be a much-needed solution.
Few diseases stump researchers as much as Alzheimer's disease. Quite simply, nothing has worked beyond some symptomatic relief. On top of that, scientists are still uncertain about what exactly causes the disease. For example, are the characteristic beta-amyloid plaques in the brain a cause of Alzheimer's disease -- or a consequence? Any promising results are welcome to a community used to setbacks.
Experiments show that blood plasma from the young reverse age-associated cognitive declines. What ingredient make it possible?
It sounds like something out of a science fiction movie, or the mind of a researcher gone off the rails. But a series of intriguing discoveries hint that young blood may help treat problems associated with the elderly.
The only drug for ALS prolongs life by 2-3 months. Stem cells could become the Trojan horses that deliver a therapy.
Neural stem cells may provide long-term treatment of neurodegenerative diseases such as Parkinson's by cell replacement or trophic factor secretion.
