  2. Bone marrow - Wikipedia

    en.wikipedia.org/wiki/Bone_marrow

    In adults, red marrow is found mainly in the central skeleton, such as the pelvis, sternum, cranium, ribs, vertebrae and scapulae, and variably found in the proximal epiphyseal ends of long bones such as the femur and humerus. In circumstances of chronic hypoxia, the body can convert yellow marrow back to red marrow to increase blood cell ...

    en.wikipedia.org/wiki/Haematopoietic_system

    Haematopoietic stem cell transplantation (HSCT) is the transplantation of multipotent haematopoietic stem cells, usually derived from bone marrow, peripheral blood, or umbilical cord blood. [ 10 ] [ 11 ] [ 12 ] It may be autologous (the patient's own stem cells are used), allogeneic (the stem cells come from a donor) or syngeneic (from an ...

  4. Bone marrow failure - Wikipedia

    en.wikipedia.org/wiki/Bone_marrow_failure

    Bone marrow failure in both children and adults can be either inherited or acquired. Inherited bone marrow failure is often the cause in young children, while older children and adults may acquire the disease later in life. [3] Acquired bone marrow failure may be due to aplastic anemia [4] or myelodysplastic syndrome.

  5. Erythropoietin - Wikipedia

    en.wikipedia.org/wiki/Erythropoietin

    Erythropoietin (/ ɪ ˌ r ɪ θ r oʊ ˈ p ɔɪ. ɪ t ɪ n,-r ə-,-p ɔɪ ˈ ɛ t ɪ n,-ˈ iː t ɪ n /; [1] [2] [3] EPO), also known as erythropoetin, haematopoietin, or haemopoietin, is a glycoprotein cytokine secreted mainly by the kidneys in response to cellular hypoxia; it stimulates red blood cell production (erythropoiesis) in the bone marrow.

    This condition is caused by the deceased liver's decreased ability to esterificate cholesterol. [61] Thalassemia: D56: D013789 Thalassaemia is an inherited blood disorder which is caused by genetic mutations that causes the body to make fewer healthy red blood cells and less hemoglobin due to lack of protein chains. Triosephosphate isomerase ...

  7. Hematopoietic stem cell - Wikipedia

    en.wikipedia.org/wiki/Hematopoietic_stem_cell

    The red bone marrow is derived from the layer of the embryo called the mesoderm. Haematopoiesis is the process by which all mature blood cells are produced. It must balance enormous production needs (the average person produces more than 500 billion blood cells every day) with the need to regulate the number of each blood cell type in the ...

  8. Bone - Wikipedia

    en.wikipedia.org/wiki/Bone

    Bone marrow, also known as myeloid tissue in red bone marrow, can be found in almost any bone that holds cancellous tissue. In newborns , all such bones are filled exclusively with red marrow or hematopoietic marrow, but as the child ages the hematopoietic fraction decreases in quantity and the fatty/ yellow fraction called marrow adipose ...

    Hematopoiesis then moves to the bone marrow at E18 in mice and 12wpc in humans, where it will reside permanently for the remainder of the individual's lifetime. In mice, there is a shift from the fetal liver to the spleen at E14, where it persists for many weeks postnatally while it occurs simultaneously in the bone marrow. [35]
