Megakaryocyte-stromal cell interactions: Effect on megakaryocyte proliferation, proplatelet production, and survival.

Bone marrow stromal cells provide a proper environment for the development of hematologic lineages. The incorporation of different stromal cells into in vitro culture systems would be an attractive model to study megakaryopoiesis and thrombopoiesis. Our objective was to evaluate the participation of different types of stromal cells in in vitro megakaryopoiesis, thrombopoiesis, and megakaryocyte (MK) survival.
