galactic cosmic ray (GCR) radiation on human hematopoietic stem cells (HSCs) tagged posts

In vitro and in vivo assessment of direct effects of simulated solar and galactic cosmic radiation on human hematopoietic stem/progenitor cells. Leukemia, 2016; DOI: 10.1038/leu.2016.344

Using mice transplanted with human stem cells, a team has demonstrated for the first time that the radiation encountered in deep space travel may increase the risk of leukemia in humans. With funding from NASA, researchers at the Wake Forest Institute for Regenerative Medicine and colleagues are using human stem cells to measure the effects of deep space radiation. “Our results are troubling because they show radiation exposure could potentially increase the risk of leukemia in two ways,” said A/Prof. Christopher Porada, Ph.D.

As part of this ongoing project, the group has identified and is currently testi...
