• Resumen

  • The article discusses research on senescent cells and how they can contribute to aging, increase inflammation, and potentially damage adjacent cells through the promotion of cancer cells. Topics include how biologist Leonard Hayflick speculated that cells cease dividing to prevent the proliferation of damaged cells and how researchers in the 1970s discovered that cell division ends when telomeres are reduced beyond a set length. Additional information is presented on biologist Judith Campisi's hypothesis that senescent cells foster tumor growth and produce other damages to cells. INSET: Good Cells Gone Bad.
