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...

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...

Overview of Hematopoiesis

Overview of Hematopoiesis

Hematopoiesis, or blood cell production, is a vital biological process that begins early in embryonic development and continues throughout life. This process generates the various types of cells found in blood, including red blood cells, white blood cells, and platelets from hematopoietic stem cells (HSCs).
Developmental Phases of Hematopoiesis
Initially, HSCs are formed in the embryonic yolk sac, a critical site for early blood cell production. These stem cells subsequently migrate to other...

Stem Cell Niche

Stem Cell Niche

The stem cell niche is the dynamic microenvironment where stem cells reside. Inside these niches, the cells may remain undifferentiated, undergo high self-renewal, or become lineage-specific progenitors. Stem cells coexist with other niche cells, such as stromal cells. They also interact closely with the ECM. Cell-cell and cell-matrix communication occur via adhesion molecules or soluble factors that signal the stem cells and determine their fate. Stromal cells also provide survival signals to...

Stem Cell Therapy for Tissue Regeneration

Stem Cell Therapy for Tissue Regeneration

Stem cell therapy is a method used in regenerative medicine to repair and restore function to damaged tissues and organs. Stem cells have the potential to proliferate and differentiate into various tissue types, making them ideal candidates for tissue regeneration. For example, hematopoietic stem cell transplants are commonly used in blood cancer treatment to replenish damaged bone marrow and restore healthy blood cells.

Bone Marrow Sampling and Transplants

Bone Marrow Sampling and Transplants

Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy the...

Summary

Bone marrow contains more than hematopoietic stem cells (HSC). It also harbors diverse non-hematopoietic stem cells, often identified by various names due to differing research approaches.

Area of Science:

Stem cell biology
Hematology
Regenerative medicine

Background:

Bone marrow (BM) is traditionally recognized as the primary niche for hematopoietic stem cells (HSCs).
Emerging evidence suggests the presence of additional stem cell populations within the BM microenvironment.
Understanding the full spectrum of stem cells in BM is crucial for regenerative medicine and disease research.

Purpose of the Study:

To review current perspectives on the bone marrow stem cell compartment.
To highlight the existence and heterogeneity of non-hematopoietic stem cells in BM.
To reconcile the various terminologies used for these distinct stem cell populations.

Main Methods:

Literature review of studies investigating bone marrow stem cells.
Analysis of data describing different types of non-hematopoietic stem cells.
Comparative assessment of experimental strategies used for stem cell identification.

Main Results:

Bone marrow harbors not only HSCs but also a diverse array of non-hematopoietic stem cells.
These non-hematopoietic stem cells have been described under multiple names, including endothelial progenitor cells (EPCs), mesenchymal stem cells (MSCs), multipotent adult progenitor cells (MAPCs), MIAMI cells, MACS, and VSEL stem cells.
It is probable that different research methods have identified overlapping or similar stem cell populations, leading to varied nomenclature.

Conclusions:

The bone marrow stem cell compartment is more complex than previously thought, including various non-hematopoietic stem cell types.
Standardization of terminology and experimental approaches is needed to better characterize these cells.
Further research into these diverse stem cell populations may unlock new therapeutic potentials.
