Summary
Aging impairs stem cell function, affecting tissue repair and regeneration. This review examines age-related declines in stem cell self-renewal and tissue homeostasis in mice.
Area of Science:
- Gerontology
- Developmental Biology
- Cell Biology
Background:
- Adult stem cells possess self-renewal and differentiation capacities crucial for tissue maintenance and repair.
- Stem cell function naturally declines with age, impacting organ function and regeneration.
- Understanding these age-related changes is vital for addressing tissue degeneration.
Purpose of the Study:
- To review the impact of aging on five key adult murine stem cell populations.
- To explore age-associated declines in stem cell self-renewal, tissue homeostasis, and regeneration.
- To examine transcriptional alterations in aged stem cells and identify future research directions.
Main Methods:
- Literature review of studies on adult murine stem cell populations.
- Analysis of age-related functional declines in stem cell self-renewal and differentiation.
- Examination of transcriptional changes reported in aged stem cells.
Main Results:
- Aging leads to functional decline in adult stem cells, compromising tissue repair.
- Specific stem cell populations exhibit distinct age-related deficits in self-renewal and regenerative capacity.
- Transcriptional profiles of aged stem cells reveal molecular changes associated with functional impairment.
Conclusions:
- Age-related stem cell dysfunction is a significant factor in reduced organ function and impaired tissue regeneration.
- Further research into the molecular mechanisms underlying stem cell aging is warranted.
- Targeting age-related stem cell changes may offer therapeutic strategies for regenerative medicine.

01:14Maintenance of the ES Cell State
2.8K
The cells of the blastocyst inner cell mass only remain pluripotent for a short time. This state of pluripotency and self-renewal can be maintained in embryonic stem (ES) cell culture by adding specific chemicals or growth factors to ensure the cells can continue dividing and later differentiate into different cell types. In some cases, the cells are grown on a feeder layer of differentiated cells, which provides the growth factors and extracellular matrix components necessary for stem cell...

02:15Replicative Cell Senescence
4.5K
Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds...

01:19The Effect of Aging on Tissues
3.9K
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...

01:32Chromatin Modification in iPS Cells
2.2K
Chromatin modification alters gene expression; therefore, scientists can add histone-modifying enzymes, histone variants, and chromatin remodeling complexes to somatic cells to aid reprogramming into pluripotent stem (iPS) cells.
Compact chromatin makes reprogramming difficult. Enzymes, such as histone demethylases and acetyltransferases, are often added during reprogramming to loosen the chromatin, making the DNA more accessible to transcription factors. Molecules that inhibit histone...

01:29Somatic to iPS Cell Reprogramming
2.7K
Reprogramming alters the gene expression in somatic cells, transforming them into induced pluripotent stem (iPS) cells over several generations. Scientists can reprogram cells by introducing genes for four transcription factors—Oct4, Sox2, Klf4, and c-Myc (OSKM) by viral or non-viral methods. These factors are also known as Yamanaka factors after Shinya Yamanaka, who first generated iPS cells using mouse skin cells. Yamanaka was awarded the Nobel Prize in Physiology or Medicine in 2012...

01:19Multipotency of Hematopoietic Stem Cells
3.9K
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...
