What is the role of senescent cells in aging?

In 1961, researchers first demonstrated that human cells have a finite capacity for division before entering a state of irreversible growth arrest. This phenomenon, known as cellular senescence, has emerged as a key factor in understanding the intricate question: **what is the role of senescent cells in aging?** These non-dividing cells accumulate with age, playing both beneficial and detrimental roles in the body's tissues.
