Senescent cells are constantly created and destroyed in all tissues of the body throughout life, but the number present at any given time increases with age, in large part because the immune system ceases to clear senescent cells as efficiently as it should. Senescent cells secrete pro-growth, pro-inflammatory factors that are useful in the short term, such as during wound healing, or to draw attention to potentially cancerous cells. When kept up for the long term, however, the signaling of senescent cells is highly disruptive to tissue structure and function. The example given here, of disrupted intestinal stem cell function …
