Telomere damage, epigenetic dysregulation, DNA damage, and mitochondrial dysfunction are primary drivers of damage in aging. Several of these drivers of damage can induce senescence. Senescence can in turn drive the consequential aging hallmarks in response to damage: stem cell exhaustion and chronic inflammation.
Consequently, what is cellular aging theory?
Cellular theories of aging propose that human aging is the result of cellular aging, whereby an increasing proportion of cells reach senescence, a terminal stage at which cells will cease to divide. This will limit the body’s ability to regenerate and to respond to injury or stress.
Senescence is a cellular process that limits a cell’s ability to multiply. It usually happens when stress factors cause substantial damage to a cell. A senescent cell is alive but cannot divide. It has an active metabolism and secretes signaling molecules to communicate with other cells.

Is cellular aging normal?
Cells shrink. If enough cells decrease in size, the entire organ atrophies. This is often a normal aging change and can occur in any tissue. It is most common in skeletal muscle, the heart, the brain, and the sex organs (such as the breasts and ovaries).
