STANFORD, Calif. — Communication is critical. Garbled in, garbled out, so to (mis-)speak. Workers who get incomplete instructions produce an incomplete product, and that’s exactly what happens with the stem cells in our aging muscles, according to researchers from the Stanford University School of Medicine.
Their study found that, as we age, the lines of communication to the stem cells of our muscles deteriorate and, without the full instructions, it takes longer for injured muscles to heal. Even then, the repairs aren’t as good. But now that the researchers have uncovered the conduit that conveys the work orders to muscle stem cells, that knowledge could open the door to new therapies for injuries in a host of different tissues.
