In 1961, Hayflick and Moorhead discovered the bounded nature of cellular proliferation, demonstrating that human cells underwent cellular senescence after roughly 60 rounds of division (now termed the “Hayflick limit”)[52]. It was later discovered that a major contributor to cellular senescence is ...
As we get older, however, this process gradually diminishes and eventually backfires. As more and more cells reach the Hayflick limit or get damaged and enter senescence—including theimmune cellsthat perform the clean-up—the sheer quantity of senescent cells overwhelms the body’s ability to cl...

Our cells can only do this 40 – 60 times, a limit known as the Hayflick limit. Immortal cells get this way either naturally, or it is induced by tweaking the genome. The supply is also a pure population of cells, which is important for consistency in repeated experiments. They can be...
and this leads to the progressive and cumulative loss of telomere-protective sequences from chromosome ends. Telomere exhaustion explains the limited proliferative capacity of some types of in-vitro-cultured cells, the so-called replicative senescence, or Hayflick limit (Hayflick and Moorhead, 1961; ...
The term was then used by Hayflick and Moorhead in 1961, to describe the specific cellular property of finite proliferative potential (the Hayflick limit) (Hayflick and Moorhead 1961). Subse- quently, a variety of additional terms have emerged includ- ing, but not limited to, cell senescence,...
