The cell division limit that is known as the Hayflick limit is the maximum number of times a cell can divide before undergoing cell death or becoming senescent. This limit is related to the shortening of telomeres, which are protective structures found at the ends of chromosomes. As cells divide, their telomeres become progressively shorter, eventually triggering a genetic program that leads to cell aging and death. The Hayflick limit varies depending on the type of cell and species, but for human cells, it is estimated to be around 50 to 70 divisions.
