    A Hierarchical Stem-Cell System: Blood Cell Formation

    40.1 : Overview of the Vascular System01:20

    40.1 : Overview of the Vascular System

    The vascular system comprises an extensive network of arteries, capillaries, and veins. The vascular system can be broadly divided into the blood and ...

    40.2 : Mechanism of Angiogenesis

    Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called ...

    40.3 : Regulation of Angiogenesis and Blood Supply

    Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or ...

    40.5 : Multipotency of Hematopoietic Stem Cells01:19

    40.5 : Multipotency of Hematopoietic Stem Cells

    The hematopoietic stem cells or HSCs are multipotent, meaning they can differentiate and give rise to all blood and immune cells. HSCs are maintained in ...

    40.7 : Erythropoiesis01:14

    40.7 : Erythropoiesis

    Red blood cells  (RBCs) transport oxygen to all body tissues. These cells survive only for 120 days and then need to be replenished. Erythropoiesis ...

    40.9 : Regulation of Hematopoietic Stem Cells

    All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a ...
