University of Cambridge Researchers Find Way to Reverse Impact of Aging on Stem Cells in Rat Brains

August 16, 2019

Researchers in the United Kingdom led by Drs. Robin Franklin and Kevin Chalut were able to reverse the negative impacts of aging on stem cells that reside in the brains of rats. Previous research by this team and others found that the brain’s stem cells, which can act as replacement parts for damaged brain tissues, lose some of their ability to repair tissues with age.
 
Through a series of lab experiments, the team found that aging cells were rejuvenated if the surrounding brain tissue was soft as in younger brains, but that younger cells would lose their ability to fully function as repair cells if surrounded by the stiffness of aging brains. The team devised a way to “trick” aging stem cells into acting as if the environment was young, and the cells regained some repair properties. If confirmed with further study, this research provides important information that could be used to develop strategies for promoting brain tissue repair and restoring function in people with MS and other disorders. The study was funded by the UK MS Society and others.

About Multiple Sclerosis

Multiple sclerosis is an unpredictable, often disabling disease of the central nervous system that disrupts the flow of information within the brain, and between the brain and body. Symptoms range from numbness and tingling to blindness and paralysis. The progress, severity and specific symptoms of MS in any one person cannot yet be predicted, but advances in research and treatment are leading to better understanding and moving us closer to a world free of MS. Most people with MS are diagnosed between the ages of 20 and 50, with at least two to three times more women than men being diagnosed with the disease. MS affects more than 2.3 million people worldwide.
