Immortality of cells

Immortality of cells refers to the ability of certain cells to divide indefinitely without aging or dying. This phenomenon is often observed in cancer cells and specific normal cells like stem cells. Typically, most cells can only divide a limited number of times before they stop, a process known as the Hayflick limit. Immortal cells may bypass this limitation due to alterations in their genetic material, allowing them to continually reproduce. This characteristic is significant in research and medicine, as it can lead to advancements in cancer treatment and regenerative therapies.
