Limitless replicative potential in cancer
Nettet1. jan. 2007 · Another process through which cancer cells acquire a limitless replicative potential or unregulated self-renewal is by cancer stem cells, which are characterized … Cancer cells have defects in the control mechanisms that govern how often they divide, and in the feedback systems that regulate these control mechanisms (i.e. defects in homeostasis). Normal cells grow and divide, but have many controls on that growth. They only grow when stimulated by growth factors. If they are damaged, a molecular bra…

Nettet1. jan. 2011 · 5 Limitless Replicative Potential and Senescence Normally, cell replication is limited to 50–70 passages ( 20 ). However, cancer cells are immortalised and capable of exceeding this limit – which is also known as the “Hayflick phenomenon” or “replicative senescence”, first recognised by Hayflick and Moorehead in the 1960s ( 21 ).
