- Megakaryocytopoiesis is the process by which stem cells go through a process of commitment, proliferation and differentiation leading to the production of platelets. In the mouse, this process is accomplished within the bone marrow (BM) and spleen microenvironment and is carried out by regulatory molecules and accessory cells including macrophages, fibroblasts and endothelial-like cells. Previously, we have reported that macrophage depletion following administration of liposomal clodronate (LIP-CLOD) provokes enhancement of both, megakaryocytopoiesis and thrombocytopoiesis. In this report, we investigated the changes in the compartment of megakaryocyte progenitor cells (MK-CFU), their correlation with plasmatic thrombopoietin (TPO) and TPO transcription levels after macrophage depletion. LIP-CLOD-treated mice showed an increase of the MK-CFU in BM and spleen. Concerning TPO plasma levels, kinetic studies revealed a 1.5- and 1.3-fold increase in the TPO concentration at 12 and 24 hr of treatment. We also show evidence of regulation of TPO transcription in the liver and spleen. Although empty liposomes also enhanced TPO gene regulation in these organs, transcriptional TPO up regulation correlated with an increase of protein synthesis only in those animals where macrophages were effectively removed. Taken together, these results suggest that BM and spleen macrophages derived signalling regulates negatively the megakaryocyte compartment
