cellular senescence

Cellular senescence is a natural process where cells lose the ability to divide and grow. It can occur in response to stress, damage, or aging. While these cells stop multiplying, they don't die off; instead, they release substances that can affect surrounding cells, potentially leading to inflammation and tissue dysfunction. Senescence plays a role in aging and various age-related diseases, but it also contributes to wound healing and preventing the spread of damaged cells, which could lead to cancer. Understanding senescence is crucial for research into healthy aging and disease prevention.
