Erythropoiesis (from Greek 'erythro' meaning "red" and 'poiesis' "to make") is the process which produces red blood cells (erythrocytes), which is the development from erythropoietic stem cell to mature red blood cell. It is stimulated by decreased O2 in circulation, which is detected by the kidneys, which then secrete the hormone erythropoietin. This hormone stimulates prolif… WebMegakaryocytes (yellow circles) can be seen at low power. B) 1,000× view. Note …

WebMay 25, 2024 · During terminal maturation, erythroid precursor cells undergo chromatin condensation, nuclear polarization to one side of the cell followed by the formation of a contractile ring that ultimately triggers nuclear expulsion and generation of an enucleated reticulocyte. 3-7 The reticulocyte begins maturation within the bone marrow and is ... WebMay 26, 2024 · Differentiation of hematopoietic stem cells to red blood cells is a continuous process with multiple distinct stages of development. During this process, cells express stage-specific genes, which are critical to regulate the complex process of stem cell commitment to erythroid differentiation and subsequent terminal erythroid … jesus loves me lullaby teddy bear
