Age-associated changes in the ecological niche: implications for mesenchymal stem cell aging
Stem Cell Research & Therapy
|May 16, 2013
Summary
Aging diminishes the effectiveness of mesenchymal stem cells (MSCs) for tissue repair. Their functional decline may be linked to changes within their natural cellular environment, known as the ecological niche.
Area of Science:
- Stem cell biology
- Regenerative medicine
- Gerontology
Background:
- Adult stem cells are vital for tissue regeneration and self-renewal, but their function declines with age.
- Mesenchymal stem cells (MSCs) show promise for regenerative therapies and are in clinical trials.
- Evidence suggests that MSC efficacy is compromised by the natural aging process.
Purpose of the Study:
- To discuss the mechanisms and manifestations of age-associated deficiencies in MSC efficacy.
- To explore the role of the ecological niche in MSC aging.
Main Methods:
- Review of experimental findings on MSC aging.
- Analysis of age-associated changes in MSC function.
- Investigation of the influence of the stem cell niche on aging.
Main Results:
- MSC efficacy is demonstrably limited by natural aging.
- Age-associated deficiencies affect MSCs' regenerative capabilities.
- The stem cell ecological niche is implicated as a potential cause of MSC aging.
Conclusions:
- Aging significantly impairs MSC function, limiting their therapeutic potential.
- Understanding the mechanisms of MSC aging is crucial for improving regenerative therapies.
- The stem cell niche warrants further investigation as a key factor in MSC aging.

01:26Stem 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...
01:19Mesenchymal Stem Cells
Mesenchymal stem cells (MSCs) are adult stem cells that can differentiate into most connective tissue cell types, except for hematopoietic cells, depending upon the source of MSCs. For example, bone-marrow-derived MSCs (BM-MSCs) can differentiate into osteocytes, hepatocytes, and pancreatic and neuronal cells. MSCs can be isolated from various sources such as bone marrow, placenta, adipose tissue, teeth, and Wharton’s jelly, a gelatinous substance in the umbilical cord. The ease of their access...
01:19Multipotency 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...
01:19The Effect of Aging on Tissues
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...
01:06Multipotency 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...
