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...

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...

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...

Multipotency and Niche of Bulge Stem Cell

Multipotency and Niche of Bulge Stem Cell

A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...

Background:

Cell migration is vital for development, cancer, and healing, but current assays study factors independently.
Understanding cell motility requires observing responses to multiple simultaneous cues.

Purpose of the Study:

To develop a novel cell motility assay for competitive recruitment by multiple chemotactic cues.
To enable simultaneous screening of various factors influencing cell migration under real-time imaging.

Main Methods:

A new device generates independent, uniform gradients of multiple chemotactic cues.
Bone marrow mesenchymal stem/stromal cells (MSCs) were exposed to 15 cytokines.
Competitive assays determined the most potent chemotactic factors based on migration metrics.

Main Results:

The potency of cytokines in competition often differed from their individual effects.
Synergistic or antagonistic interactions between cues were observed.
The assay identified key factors driving MSC migration in an arthritis model.

Conclusions:

Simultaneous testing is essential to accurately assess chemotactic factor potency due to complex interactions.
This assay is valuable for screening cell migration-inducing molecules in drug development and regenerative medicine.
The device provides a more realistic model for studying cell migration in complex biological environments.
