Hayflick 1961
WebAt the time of the experiment's publication in 1961, Hayflick hypothesized that cells had intrinsic factors that determined aging. However, he and Moorhead did not rule out the possibility that viruses interfered with the cells and caused the cells to stop dividing. WebNov 13, 2008 · Leonard Hayflick, the biogerontologist who in 1961 discovered the limit on cell division that bears his name, says he agrees that the new research shows that …
