Some blood cells have a surprising source—your gut

The human intestine may provide up to 10 percent of blood cells in circulation from its own reservoir of blood-forming stem cells, a surprising new study from researchers at Columbia University Vagelos College of Physicians ...

Mouse model of human immune system inadequate for stem cell studies

A type of mouse widely used to assess how the human immune system responds to transplanted stem cells does not reflect what is likely to occur in patients, according to a study by researchers at the Stanford University School ...

Experts uncover first molecular events of organ rejection

Researchers at the University of Pittsburgh School of Medicine and the University of Toronto have uncovered the first molecular steps that lead to immune system activation and eventual rejection of a transplanted organ. The ...
