The presence of senescent cells causes age-related pathologies since their removal by genetic or pharmacological means, as well as possibly by exercise, improves outcomes in animal models. An alternative to depleting such cells would be to rejuvenate them to promote their return to a replicative state. Here we report that treatment of non-growing senescent cells with low-frequency ultrasound (LFU) rejuvenates the cells for growth. Notably, there are 15 characteristics of senescent cells that are...

CONCLUSION: In wrist and ankle joints, the age-related decline in proprioception is limited to the sense of force, especially for low forces. This nonuniform decline in proprioception across proprioceptive senses and testing conditions could reflect a decline in the central processing of proprioceptive information.
