immortal cells

Immortal cells are cells that can divide an unlimited number of times, unlike most cells that have a limited lifespan. This means they can grow and reproduce indefinitely under the right conditions. Scientists often study immortal cells, like cancer cells or those used in lab research, because they can be maintained long-term. These cells continue to divide without aging or dying, allowing for consistent, ongoing experiments. The ability to keep dividing is due to changes in their biology, such as maintaining specific structures like telomeres, which normally limit cell lifespan.
