quiescence - Longevity Clips

Cellular quiescence (reversible cell cycle arrest) occurs due to lack of nutrition and growth factors whereas senescence takes place due to aging and serious DNA damage. Contrary to quiescence, senescence is a degenerative process ensuing a certain cell death.

Study Demonstrates Age Reversal through Cellular Reprogramming with Chemical Cocktails – David Sinclair
A team of scientists from Harvard Medical School discovered a method to distinguish young cells from old and senescent cells in real time. This allowed them to quickly screen the effect of different molecules on cellular health. Using this method, they were able to identify 6 different combinations of molecules that can be used to “reset” the age of cells to a youthful, healthy state.
