Stem Cells from Fat Cells May Help Reverse Aging

Highlights

Stem cells derived from variety of tissues are currently used in various anti-aging treatments.
But stem cells derived from human fat cells called adipose-derived stem cells (ASCs) are more stable that other cells.
This ASCs can make more proteins which gives them the ability to replicate and maintain their stability.

Adult stem cells collected directly from human fat called adipocytes are more stable than other cells and have the potential for use in anti-aging treatments.

The findings are according to researchers from the Perelman School of Medicine at the University of Pennsylvania.

Wrinkles and Anti-Wrinkle Treatments - Causes, Treatment, Types, Effectiveness
Anti-wrinkle treatments are for the repair of deep wrinkles, crow’s feet and aging, for youthful skin. The procedures are laser wrinkle removal, anti wrinkle creams and other anti aging products.

Stem cells are commonly derived from variety of tissues such as skin called fibroblasts are currently used in a variety of anti-aging treatments.

But the research team led by Ivona Percec found that stem cells collected directly from human fat called adipose-derived stem cells (ASCs) are more stable that other cells.

These findings can potentially open the door to new therapies for the prevention and treatment of aging-related diseases.

Cutting Down Calories Slows Aging Process in Mice
Reducing calorie intake slows down production of ribosomes but gives it extra time to repair themselves which increases longevity.

Method

The researchers developed a new model to study chronological aging of these cells.

Aging Experiences of LGBT Americans
LGBT older adults face disparities in health and well-being compared to heterosexual peers, including higher rates of disability, cardiovascular disease, etc.

Chronological aging shows the natural life cycle of the cells rather than unnaturally replicating or manipulating the cells multiple times in a lab.

Penn researchers developed a system to collect and store the cells to preserve them in their natural state without manipulating them thus making them available for this study.

A hormone called DHEAS makes you live longer - but only if you are 'wealthy' enough, if a new study is to be believed.

The researchers found that adipose-derived stem cells (ASCs) can make more proteins which gives them the ability to replicate and maintain their stability.

These finding were found to be true in cells collected from patients of all ages.

"Our study shows these cells are very robust, even when they are collected from older patients," said Ivona Percec, MD, director of Basic Science Research in the Center for Human Appearance and the study's lead author.

This shows that these cells can be potentially used safely in the future, because they require minimal manipulation and maintenance.

"Unlike other adult human stem cells, the rate at which these ASCs multiply stays consistent with age," Percec said. "That means these cells could be far more stable and helpful as we continue to study natural aging."

Conclusion

More research is needed as ASCs are not currently approved for direct use by the Food and Drug Administration.

The next step in the research is to study how chromatin is regulated in ASCs by understanding how tightly the DNA is wound around proteins inside these cells and how this affects aging.

The more open the chromatin is, the more the traits affected by the genes inside will be expressed.

Percec said she hopes to find out how ASCs can maintain an open profile with aging.

The findings are published in the journal Stem Cells.
