    Insights

    Aging impairs stem cell function, particularly hematopoietic stem cells (HSCs), through epigenetic dysregulation. These changes are heritable, potentially leading to clonal hematopoiesis and blood diseases in the elderly.

    Area of Science:

    • Gerontology
    • Stem Cell Biology
    • Epigenetics

    Background:

    • Aging is linked to stem cell dysfunction, with hematopoietic stem cells (HSCs) extensively studied.
    • Epigenetic regulation is crucial for stem cell maintenance.
    • Dysregulation of epigenetic mechanisms contributes to age-related stem cell decline.

    Purpose of the Study:

    • To review recent research on the epigenetic regulation of HSCs during aging.
    • To highlight the role of epigenetic alterations in HSC functional decline.

    Main Methods:

    • Literature review of recent studies.
    • Focus on epigenetic mechanisms in aging HSCs.

    Main Results:

    • Epigenetic dysregulation is a central factor in aging-related HSC functional decline.
    • Altered stem cells are perpetuated through self-renewal and transmitted to progeny.
    • These alterations can lead to clonal hematopoiesis and increase the risk of hematopoietic diseases.

    Conclusions:

    • Epigenetic modifications play a critical role in HSC aging.
    • Understanding these epigenetic changes is key to addressing age-related stem cell dysfunction and associated diseases.

    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 the quiescent stage until an external stimulus initiates their differentiation. The multipotent HSCs exist as two heterogeneous populations, long-term repopulating cells (LTRC) and short-term repopulating cells (STRC). The two HSC populations have different surface markers or receptors and are classified based on quiescence and long-term...

    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 limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...

    Role of Hematopoietic Growth Factors01:28

    Role of Hematopoietic Growth Factors

    Hematopoietic growth factors are molecules that regulate the differentiation rate of hematopoietic stem cells (HSCs). Erythropoietin (EPO), primarily produced by the kidneys, plays a crucial role in erythrocyte production. When oxygen levels in the blood are low, EPO is released into the bloodstream, reaching the bone marrow, where it stimulates HSCs to differentiate and mature into erythrocytes, which are vital for oxygen transport.
    Thrombopoietin (TPO), mainly released by the liver,...

    Adult Stem Cells01:33

    Adult Stem Cells

    Stem cells are undifferentiated cells that divide and produce more stem cells or progenitor cells that differentiate into mature, specialized cell types. All the cells in the body are generated from stem cells in the early embryo, but small populations of stem cells are also present in many adult tissues including the bone marrow, brain, skin, and gut. These adult stem cells typically produce the various cell types found in that tissue—to replace cells that are damaged or to continuously...

    Embryonic Stem Cells

    Embryonic stem (ES) cells are undifferentiated pluripotent cells, meaning they can produce any cell type in the body. This gives them tremendous potential in science and medicine since they can generate specific cell types for use in research or to replace body cells lost due to damage or disease.

    Induced Pluripotent Stem Cells

    Stem cells are undifferentiated cells that divide and produce different types of cells. Ordinarily, cells that have differentiated into a specific cell type are post-mitotic—that is, they no longer divide. However, scientists have found a way to reprogram these mature cells so that they “de-differentiate” and return to an unspecialized, proliferative state. These cells are also pluripotent like embryonic stem cells—able to produce all cell types—and are therefore...
