The genetically anemic W/Wv mice are characterized by the inability of their bone marrow cells to form macroscopic pluripotent hematopoietic colonies in the spleen of irradiated recipients upon transfer (colony-forming units). Furthermore, they almost totally lack mast cells, notably in the skin. In the present study, we have tested the effect of recombinant murine interleukin 3 (rmIL-3) on W/Wv mice hematopoiesis. Transfer of W/Wv bone marrow cells into lethally irradiated recipients perfused with rmIL-3 is followed by the appearance of macroscopic spleen colonies. Moreover, perfusion of rmIL-3 in W/Wv mice: (a) restores almost normal total numbers of hematopoietic precursors (colony-forming cells), but without modification of anemia; and (b) leads to the appearance of a normal number of mastocytes in the skin.
Interleukin 3 perfusion in W/Wv mice allows the development of macroscopic hematopoietic spleen colonies and restores cutaneous mast cell number.
