What Was Studied

The authors analyzed the accumulated scientific data on how mesenchymal stem/stromal cells (MSCs) and the exosomes they secrete may influence the biological mechanisms of aging.

In particular, they examined genomic instability, telomere shortening, epigenetic changes, mitochondrial dysfunction, cellular senescence, depletion of the stem cell pool, chronic inflammation, and disruptions in intercellular communication.

It is particularly interesting that the authors highlight paracrine signaling as one of the most important proposed mechanisms of MSC action. MSC exosomes carry biologically active components, including proteins, mRNA, and microRNA, which can influence other cells. The article also discusses immunomodulatory mechanisms involving TGF-β and IL-10.
