The Hayflick limit is the number of times a normal human cell can divide before stopping due to telomere shortening. It was discovered by Leonard Hayflick in 1961 and refuted the myth of cell immortality.
Oct 1, 2000 · 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 ...

Leonard Hayflick introduced the hayflick limit as the number of times a cell population can divide until it attains a cell cycle arrest. It is found to correlate with end regions of DNA strand called telomeres as telomeres get shorter by each cell division.

Apr 16, 2024 · The Hayflick limit is the maximum number of times a cell can divide before dying. Learn how this limit is related to aging, apoptosis, telomeres and telomerase, and why it may be impossible to overcome.
Nov 14, 2014 · The Hayflick Limit is a concept that helps to explain the mechanisms behind cellular aging. The concept states that a normal human cell can only replicate and divide forty to sixty times before it cannot divide anymore, and will break down by programmed cell death or apoptosis.
Jun 18, 2011 · Leonard Hayflick, professor of anatomy at the University of California at San Francisco, advanced the concept 50 years ago. The Hayflick Limit, he contended, was both an explanation for the phenomenon of ageing and a demolition of the wishful view (of some) that the human lifespan need have no upper limit.
Hayflick limit or Hayflick’s phenomena is defined as the number of times a normal cell population divides before entering the senescence phase. Macfarlane Burnet coined the term “c limit” in 1974.
