Abstract
Under normal physiological conditions, hematopoietic stem cells (HSC) are sequestered in a hypoxic microenvironment in the bone marrow (BM), suggesting that low oxygen levels may play a fundamental role in the maintenance of normal stem cell function and protect these cells from the damaging effects of reactive oxygen species (ROS). In vitro culture of human BM CD34+ cells under hypoxic conditions has been shown to result in expansion of SCID-repopulating cells (SRC) as compared to culture under normoxic conditions (
