Effect of prolonged exposure to a magnetic field on the haematopoietic stem cell.
The authors studied the effect of prolonged exposure (3, 4 and 5 months) to the action of a magnetic field of 180-200 gauss formed by the poles of a rotating permanent magnet on the haematopoietic stem cells of mouse bone marrow donors. The effect of the field was evaluated from the ability of the donors' bone marrow cells to form haematopoietic colonies in the spleen of lethally irradiated mice. It was found that the number of stem cells was not reduced by the action of the above magnetic field and that proliferative capacity was likewide unimpaired.
