Hematopoiesis

Hematopoiesis

The process of blood cell formation is called hematopoiesis. Hematopoiesis starts early during development, on the seventh day of embryogenesis. This phase of hematopoiesis is called the primitive wave, wherein the extraembryonic yolk sac allows the production of erythroid cells and endothelial cells from a common precursor called hemangioblast. The erythroid cells provide oxygen to support the growth of the rapidly dividing embryo. Hemangioblasts later develop into hematopoietic stem cells or...

Differentiation of Common Myeloid Progenitor Cells

Differentiation of Common Myeloid Progenitor Cells

Common myeloid progenitors (CMPs) are oligopotent cells that can differentiate into granulocytes and macrophages. Granulocytes and macrophages are essential for protecting the body against bacterial, viral, or fungal infections. They migrate from the bone marrow into the circulating blood to reach specific tissue sites where they differentiate and help in immune surveillance. However, they survive only for a few days and must be continuously made available to the organism to maintain a robust...

Multipotency of Hematopoietic Stem Cells

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...

Production of Formed Elements

Production of Formed Elements

Hemangioblasts are multipotent stem cells originating from the mesoderm. They give rise to hematopoietic stem cells (HSCs), which undergo hematopoiesis to produce all the formed elements of blood. This process is regulated by a complex network of hematopoietic growth factors, including transcription factors, growth factors, and cytokines. These factors stimulate the HSCs to divide and differentiate, though some HSCs remain undifferentiated to maintain a self-renewing pool.
Most HSCs commit to...

Cell Migration

Cell Migration

Cell migration is a process by which the cells move from one location to another, playing an essential role in embryological development, repair and regeneration, immune response, and metastasis. Cells migrate in response to chemical or mechanical signals generated by specific organs or tissues. The overall mechanism includes three steps - polarization, protrusion, and release. Polarization involves the formation of a distinct cell front and rear, which determines the direction of movement.

Area of Science:

Stem cell biology and regenerative medicine.

Background:

Pathological conditions involve stem cell and progenitor cell mobilization.
Bone marrow stem cells (hematopoietic and endothelial progenitors) can mobilize and traffic.
Aging impairs bone marrow's regenerative capacity, necessitating exploration of other progenitor reservoirs.

Purpose of the Study:

To review current knowledge on non-bone marrow-derived progenitor cell pools.
To focus on mesenchymal stem cells as a key extramedullary source.
To present evidence for extramedullary progenitor mobilization, particularly from white adipose tissue.

Main Methods:

Literature review and synthesis of existing research on stem cell mobilization.
Focus on studies investigating progenitor cell populations outside the bone marrow.
Analysis of evidence supporting extramedullary mobilization, with emphasis on adipose tissue.

Main Results:

Non-bone marrow organs serve as significant reservoirs for progenitor cells.
Mesenchymal stem cells are a prominent population within these extramedullary pools.
Evidence supports the mobilization of progenitors from tissues like white adipose tissue.

Conclusions:

Understanding extramedullary progenitor pools is vital for regenerative medicine.
Mesenchymal stem cells from non-bone marrow sources offer therapeutic potential.
Adipose tissue represents a promising source for mobilized progenitor cells in disease and repair.
