The medicine of the future could be driven by mechanical cell memory
It's not a cure for baldness. But it might eliminate crow's feet and laugh lines by telling the tissues in your face how to remember their more elastic youth.
A new field of research called mechanical cell memory could revolutionize medicine. This concept, led by Ning Wang, a Northeastern University professor of bioengineering, suggests that cells can retain a memory of previously applied physical forces and continue reacting as if the force is still present. Wang demonstrated this phenomenon in his lab by using hamster cells and microscopic magnets, proving that short, repeated periods of force stimulation could produce the same cellular responses as continuous stimulation.
This discovery has several potential applications. For older individuals, mechanical memory could help improve the effectiveness of short exercise routines, allowing them to achieve the benefits of an hour-long workout in just a few minutes. Additionally, it could lead to treatments that enhance the elasticity of facial muscles and tissues, potentially reducing the appearance of crow's feet and laugh lines.
Furthermore, mechanical cell memory could be harnessed to strengthen muscles and collagen production, benefiting individuals with limited mobility. The key to this process lies in the ability of certain cells, including those in the immune system, to retain a memory of physical force and respond accordingly, even after the force has ceased.
