Adult stem cells collected directly from human fat are more stable than other cells, such as fibroblasts from the skin and have the potential for use in anti-aging treatments, according to researchers from the Perelman School of Medicine at the University of Pennsylvania.johnvlahakisapmsnyc13  Researchers made the discovery after developing a new model to study chronological aging of these cells. They published their findings in the journal Stem Cells. Chronological aging shows the natural life cycle of the cells, as opposed to cells that have been unnaturally replicated multiple times or otherwise manipulated in a lab. In order to preserve the cells in their natural state, Penn researchers developed a system to collect and store them without manipulating them, making them available for this study. They found stem cells collected directly from human fat, called adipose-derived stem cells (ASCs), can make more proteins than originally thought. This gives them the ability to replicate and maintain their stability, a finding that held true in cells collected from patients of all ages.  Stem cells are currently used in a variety of anti-aging treatments and are commonly collected from a variety of tissues. Researchers specifically found ASCs to be more stable than other cells, a finding that can potentially open the door to new therapies for the prevention and treatment of aging-related diseases.  ASCs are not currently approved for direct use by the Food and Drug Administration, so more research is needed. The next step for is to study how chromatin is regulated in ASCs. Essentially, they want to know 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. Researchers hope to find out how ASCs can maintain an open profile with aging.
