Effect of lithium on diffusion chamber granulopoiesis.
We studied the effect of lithium on diffusion chamber (DC) granulopoiesis. When DC loaded with bone marrow cells were implanted into the peritoneal cavity of mice previously injected with lithium carbonate, more proliferative and nonproliferative granulocytes were produced as compared to DC implanted into control hosts. The number of DC CFU-c was increased significantly in the lithium-treated group, but there was no difference in the number of DC CFU-s. Levels of DC fluid CSF showed no evident correlation with DC myelopoiesis. These data suggest that a humoral factor other than CSF mediates the action of lithium in DC granulopoiesis, and that lithium's influence on DC hematopoietic stem cell proliferation occurs mainly at the CFU-c level.
