cell aging

Cell aging, or senescence, refers to the gradual decline in a cell's function and ability to divide over time. As cells replicate, they accumulate damage from factors like oxidative stress and DNA mutations. Eventually, they reach a point where they stop dividing and enter a state of senescence. This process contributes to signs of aging in tissues, reduces regenerative capabilities, and may lead to age-related diseases. Factors influencing cell aging include genetics, lifestyle choices, and environmental exposure, highlighting the interplay between our biology and the world around us.
