Replicative Cell Senescence

Replicative Cell Senescence

Replicative Cell Senescence

Replicative Cell Senescence

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...

iPS Cell Differentiation

iPS Cell Differentiation

The ability of induced pluripotent stem cells or iPSCs to differentiate into most body cell types has stimulated repair and regenerative medicine research over the past few decades. iPSC-derived blood cells, hepatocytes, beta islet cells, cardiomyocytes, neurons, and other cell types can repair injuries or regenerate damaged tissue in diseases such as diabetes and neurodegenerative disorders.

The Effect of Aging on Tissues

The 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...

Adult Stem Cells

Adult Stem Cells

Stem cells are undifferentiated cells that divide and produce more stem cells or progenitor cells that differentiate into mature, specialized cell types. All the cells in the body are generated from stem cells in the early embryo, but small populations of stem cells are also present in many adult tissues including the bone marrow, brain, skin, and gut. These adult stem cells typically produce the various cell types found in that tissue—to replace cells that are damaged or to continuously...

Stem Cell Culture

Stem Cell Culture

Stem cell research aims to find ways to use stem cells to regenerate and repair cellular damage. Over time, most adult cells undergo the wear and tear of aging and lose their ability to divide and repair themselves. Stem cells do not display a particular morphology or function. Adult stem cells, which exist as a small subset of cells in most tissues, keep dividing and can differentiate into a number of specialized cells generally formed by that tissue. These cells enable the body to renew and...

Area of Science:

Gerontology and Regenerative Medicine
Cellular and Molecular Biology

Background:

Aging is a primary risk factor for geriatric diseases, involving physiological decline like neurodegeneration and cardiovascular issues.
While natural aging isn't programmed, progeria syndromes demonstrate programmed accelerated aging, offering insights into the aging process.
Werner syndrome (WS) and Hutchinson-Gilford progeria syndrome (HGPS) are key models for studying premature aging.

Purpose of the Study:

To review the role of stem cell aging in Werner syndrome for understanding general aging biology.
To discuss the potential for reversing epigenetic alterations in aged cells to a younger state.
To explore the application of genomic editing techniques in stem cell therapy for aging and regenerative medicine.

Main Methods:

Review of existing literature on stem cell aging in Werner syndrome.
Discussion of epigenetic modifications and their potential for reversal.
Exploration of genomic editing technologies for therapeutic applications in aging.

Main Results:

Stem cell aging in WS provides a model to understand fundamental aging mechanisms.
Epigenetic landscapes in aged cells show potential for rejuvenation.
Genomic editing offers promising avenues for stem cell-based regenerative therapies.

Conclusions:

Studying stem cell aging in progeria syndromes like WS is crucial for aging research.
Reversing epigenetic changes and utilizing genomic editing hold significant potential for anti-aging therapies and regenerative medicine.
