    Study Notes

    Hematopoiesis Overview

    • Hematopoiesis is the process of blood cell formation from stem cells.
    • It primarily occurs in the bone marrow.

    Hemocytoblast

    • A type of pluripotent stem cell specific for blood cell production.
    • When dividing, produces one blood cell and retains one hemocytoblast.
    • Ensures continuous availability of hemocytoblasts for ongoing blood cell generation.

    Pluripotent Stem Cells

    • Stem cells capable of differentiating into almost any tissue or cell type in the body.
    • Play a critical role in development and tissue regeneration.

    Myeloid Stem Cells

    • A subtype of stem cells derived from hemocytoblasts.
    • Responsible for producing various blood cells, including red blood cells, platelets, and some white blood cells.

    Lymphoid Stem Cells

    • Another subtype of hemocytoblasts that specifically differentiate into lymphocytes.
    • Lymphocytes are essential for the immune response, including B cells and T cells.

    CFU-E

    • Colony Forming Unit-Erythroid, a type of progenitor cell involved in the production of red blood cells.
    • Represents a critical step in the differentiation pathway of myeloid stem cells towards erythrocytes.
