immortalization

Immortalization refers to the process of preserving biological material, such as cells, tissues, or organisms, so they can be maintained indefinitely without significant changes or degradation. This is often achieved through techniques like freezing or preserving in special solutions, allowing scientists and researchers to study, replicate, or use these materials long-term. For example, immortalized cell lines are human or animal cells that can divide endlessly in a laboratory setting, providing a consistent resource for research and medical advancements. Essentially, immortalization extends the lifespan of biological samples beyond natural limits, enabling ongoing scientific exploration.
