It is now clearer that extracellular vesicles (aka exosomes) they are the primary method of communication between stem cells the other cells of the body.
I explain how aging emerges from an imbalance of cell birth, maintenance, and death, and the inevitability of time and entropy.
How telomere erosion leads to chromosomal mutation, which causes dysfunction and cell death (we hope)
Just a link for those of you who may not know what telomerase is, what it does, and why it is crucial to slow aging.
Failure to faithfully replicate and preserve stem cell DNA appears to be the final common pathway to premature aging
