WebIn 1961, cellular aging was first described by Hayflick and Moorhead. They showed that human cells in culture do not divide indefinitely but reach a limit (called the Hayflick limit) … Web-Cancer cells exhibit no limit and continue dividing indefinitely, behaving as if they were immortal Hayflick Limit The number of times a human cell is capable of dividing into 2 new cells. The limit for most human cells is approximately 50 divisions, suggesting that the life span is limited by our genetic program

They may form a mass of abnormal cells called a tumor (see Figure 7.2.4 ). The rapidly dividing cells take up nutrients and space that normal cells need. This can damage tissues and organs and eventually lead to death.
