A new study claims that low-frequency ultrasound can reverse aspects of replicative and chemically induced senescence in vitro [1].
The age-related increase in senescent cell burden is thought to contribute to many processes of aging. Most of the attempts to deal with it involve senolytics: drugs that eliminate senescent cells.
However, it may be possible to re-educate them instead. Senomorphics are compounds that change senescent cells in a way that renders them benign, but they are much less common. The authors of this new pre-print study (it has not yet been peer-reviewed) claim to have found an even more impressive way to solve the senescent cell problem: by rejuvenating them with ultrasound.
