This was first described in 1961 by Hayflick and Moorhead and is known as ‘the Hayflick phenomenon’ or replicative senescence[62]. Today, replicative senescence of lympho-haemopoietic cell populations is determined by the number of population doublings or mitoses a cell experiences during its life...
This claim defined cell death, which had been a problem leading to a laboratory failure, as a normal phenomenon. On the other hand, permanent life, which had been considered a normal cellular characteristic, became a major factor causing scientific failure, since it implied malignant transformation...

Almost 40 years ago, Leonard Hayflick discovered that cultured normal human cells have limited capacity to divide, after which they become senescent -- a phenomenon now known as the 'Hayflick limit'. Hayflick's findings were strongly challenged at the time, and continue to be questioned in a ...

He states that the professor of the University of California, San Francisco argued that the Hayflick Limit was both an explanation for the phenomenon of ageing and a demolition of the wishful view that the human lifespan need have no upper limit. He also profiles Hayflick who is now involved...
