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...

Regulation of Hematopoietic Stem Cells

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...

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...

Summary

Hematopoietic stem cells (HSCs) self-renewal is studied using functional assays. This review covers assay theory, design considerations, and provides a serial-dilution protocol for HSC quantification.

Area of Science:

* Stem cell biology
* Hematopoiesis
* Immunology

Background:

* Stem cells possess self-renewal capabilities, a critical characteristic.
* Hematopoietic stem cells (HSCs) are a well-established model for studying stem cell self-renewal.
* Functional assays are essential for identifying and quantifying HSCs.

Purpose of the Study:

* To review the theoretical underpinnings of stem cell functional assays.
* To discuss key considerations for selecting and designing these assays.
* To provide a foundational protocol for the serial-dilution assay for HSC quantification.

Main Methods:

* Review of existing literature on stem cell functional assays.
* Theoretical analysis of assay principles.
