pubmed:abstractText |
Bone marrow from 5-fluorouracil-treated mice support osteogenesis when cultured in the presence of beta-glycerophosphate and vitamin C. These cultures are unable to support the growth of granulocyte/macrophage colony-forming units for longer than 2 weeks. In contrast, granulocyte/macrophage colony-forming units were detected for more than 6 weeks in interleukin-10 (IL-10)-treated cultures. In addition, IL-10-treated cultures contain long-term culture initiating cells, suggesting the presence of pluripotent hematopoietic cells. Apparently, IL-10 does not directly stimulate the proliferation of granulocyte/macrophage colony-forming units. Interleukin-10 is unable to stimulate [3H]-thymidine incorporation or to increase the number of granulocyte/macrophage colony-forming units in cell suspensions harvested from untreated or interleukin-10-treated bone marrow cultures. Interleukin-10 acts via an indirect pathway. Because exogenous transforming growth factor-beta (TGF-beta) reverses IL-10's stimulatory activity on myeloid progenitors, IL-10 most likely works by blocking TGF-beta synthesis, which acts as an endogenous suppressor of hematopoiesis in osteogenic marrow cultures. This is shown further by the increased numbers of granulocyte/macrophage colony-forming units in cultures treated with neutralizing anti TGF-beta antibodies (1D11.16). Interleukin-10 and 1D11.16 change the cultured bone marrow stroma from an osteogenic into a hematopoietic morphology. It may be that by blocking endogenous TGF-beta production, IL-10 drives marrow mesenchymal cells away from osteogenic differentiation toward hematopoietic support.
