title: Vitamin D suppression of spleen colony formation in radiation chimeras.
abstract: The effect of vitamin D on spleen colonies in murine bone marrow chimeras was investigated using a single suprapharmacologic dose of vitamin D. The results revealed that vitamin D even without producing hypercalcemia, reduced to a significant degree the number of spleen colonies obtained. This finding is thought to be due to either a direct effect of the vitamin on the capacity of stem cells to multiply or an effect on the number of stem cells that lodge in the spleen.
