Cell senescence can be caused by a variety of factors, including normal biological aging, DNA damage, oxidative stress, telomere shortening, inflammation, and exposure to certain environmental toxins. As cells divide and replicate over time, they accumulate damage to their DNA and other cellular components, which can trigger senescence as a protective mechanism to prevent damaged cells from becoming cancerous. Additionally, environmental stressors like UV radiation, pollution, and tobacco smoke can cause cellular damage and promote senescence. Finally, chronic inflammation is also known to contribute to senescence… Read More »
