Human stem cells transformed into key neurons lost in Alzheimer’s

CHICAGO — Northwestern Medicine researchers for the first time have transformed a human embryonic stem cell into a critical type of neuron that dies early in Alzheimer’s disease and is a major cause of memory loss.
This new ability to reprogram …

How long do stem cells live?

LA JOLLA, Calif., March 1, 2011 — When patients receive a bone marrow transplant, they are getting a new population of hematopoietic stem cells. Fresh stem cells are needed when a patient is low on red blood cells, as in anemia, or white blood cel…
