HAEMATOPOIETIC THROMBOCYTE PRECURSORS IN RAT FEMORAL AND STERNAL BONE MARROW

摘要

This research presents the first findings on thrombopoiesis for Wistar rats. Haemopoietic cells from the femur and the sternum were analysed by light microscopy in combination with infrared and nearultraviolet light for fine cytoplasmic structure analysis. Five main types of thrombocyte precursor cells were identified in the bone marrow samples: megakaryoblast, promegakaryocyte and megakaryocyte (basophilic, acidophilic and thrombocytogenic). More intensive thrombopoiesis and morphologically differentiated cells were found in sternum samples.
