Gone for 73 Years But Her Cells Live On [Video]

Gone for 73 Years But Her Cells Live On #immortal. HeLa cells are extraordinary in the world of cell biology because they are immortal—they can divide indefinitely in culture, unlike normal human cells, which have a limited lifespan. This unique property makes HeLa cells invaluable for scientific research and medical advancements. The immortal nature of HeLa cells is attributed to a mutation in the TP53 gene, which regulates cell division and apoptosis (programmed cell death). In HeLa cells, this mutation allows them to bypass the normal regulatory mechanisms that limit cell division, enabling them to proliferate indefinitely under the right conditions. Moreover, HeLa cells are exceptionally robust and adaptable, able to survive and thrive in a wide range of culture conditions and environments. This resilience makes them ideal for experiments that require long-term cell culture, as well as for studying cellular processes, disease mechanisms, drug testing, and vaccine development. HeLa cells have been instrumental in research on cancer biology, virology, genetics, immunology, and countless other fields. They have been used to study the effects of radiation, test new drugs and therapies, and investigate the molecular mechanisms underlying diseases such as cancer, AIDS, and Alzheimer’s disease. #ethics #research
