  2. Haematopoietic system - Wikipedia

    The haematopoietic system (spelled hematopoietic system in American English) is the system in the body involved in the creation of the cells of blood. [1] Structure

    en.wikipedia.org/wiki/Haematopoiesis

    Diagram showing the development of different blood cells from haematopoietic stem cell to mature cells. Haematopoiesis (/ h ɪ ˌ m æ t ə p ɔɪ ˈ iː s ɪ s, ˌ h iː m ə t oʊ-, ˌ h ɛ m ə-/; [1] [2] from Ancient Greek αἷμα (haîma) 'blood' and ποιεῖν (poieîn) 'to make'; also hematopoiesis in American English, sometimes h(a)emopoiesis) is the formation of blood cellular ...

  4. Hematopoietic stem cell - Wikipedia

    en.wikipedia.org/wiki/Hematopoietic_stem_cell

    Hematopoietic stem cells (HSCs) are the stem cells [1] that give rise to other blood cells.This process is called haematopoiesis. [2] In vertebrates, the first definitive HSCs arise from the ventral endothelial wall of the embryonic aorta within the (midgestational) aorta-gonad-mesonephros region, through a process known as endothelial-to-hematopoietic transition.

  5. Blood cell - Wikipedia

    en.wikipedia.org/wiki/Blood_cell

    A blood cell (also called a hematopoietic cell, hemocyte, or hematocyte) is a cell produced through hematopoiesis and found mainly in the blood. Major types of blood cells include red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes).

  6. Thrombopoiesis - Wikipedia

    en.wikipedia.org/wiki/Thrombopoiesis

    The megakaryoblast is a platelet precursor that undergoes endomitosis to form megakaryocytes that have 8 to 64 nuclei. Megakaryocytes shed platelets into the bloodstream. β1-tubulin microtubules, which are found in megakaryocytes, facilitate this process of shedding platelets into the bloodstream. [5]

  7. Myeloid tissue - Wikipedia

    en.wikipedia.org/wiki/Myeloid_tissue

    [4] The word myelopoiesis has several senses in a way that parallels those of myeloid , and myelopoiesis in the narrower sense is the regulated formation specifically of myeloid leukocytes (myelocytes), allowing that sense of myelopoiesis to be contradistinguished from erythropoiesis and lymphopoiesis (even though all blood cells are normally ...

  8. Hematopoietic stem cell niche - Wikipedia

    en.wikipedia.org/wiki/Hematopoietic_stem_cell_niche

    Primitive hematopoiesis is first found in the blood islands (Pander's islands) of the yolk sac at E7.5 (embryonic day 7.5) in mice and 30dpc (30 days post-conception) in humans. As the embryo requires rapid oxygenation due to its high mitotic activity , these islands are the main source of red blood cell (RBC) production via fusing endothelial ...
