Hay flick limit is a number of times a human cell divides until its cell division stops. .Telomeres associated with each cell shortens with each new cell division until they shorten to critical length. .this limit was advanced by Leonard Hay flick. .he said that number of normal human fetal cells in cell culture will divide 20-40 times . the population will then enter senescence phase .each mitosis starts shortening each of Telomeres on Dna of the cells .Telomere shorting may also prevent cancer in human cells,by limiting the number of cell divisions
