As demonstrated by
Leonard Hayflick a half-century ago, human cells have a limited replicative lifespan, with older cells reaching this limit sooner than younger cells.
Not long ago, the microbiologist
Leonard Hayflick was asked what had changed since he began his career 55 years ago.
Biologists
Leonard Hayflick and Colin Blakemore appearas skeptical counterpoints.
The Hayflick limit, named after
Leonard Hayflick, is the limit on the number of times a given cell can divide.

Leonard Hayflick (born 20 May 1928) is widely known for his research in cell biology and the ageing process.
Leonard Hayflick's original observations that human body cells have a finite capacity for cell division, researchers around the world have sought to discover a means to reset that clock for diverse clinical applications," said West.
Leonard Hayflick. Audrey was a Research Fellow and Professor of Biology and Biotechnology at Worcester Polytechnic Institute in Worcester, MA from 1976 to 1983.
This phenomenon is known as the Hayflick limit, after
Leonard Hayflick, who with Paul Moorhead described it in 1961 while at the Wistar Institute in Philadelphia.
Por la misma epoca, Alexsei Matveevich Olovnikov, un desconocido cientifico ruso, hallo el eslabon entre el problema de la replicacion terminal -enunciado por Watson-y la senescencia celular, a su vez previamente descrita por
Leonard Hayflick. Segun Hayflick y Moorhead (4), la senescencia correspondia a un estado de detencion de la proliferacion, al que ingresaban las celulas somaticas humanas con signos de alteraciones bioquimicas y morfologicas como producto de haber sobrepasado su capacidad limite de division.
