TED-Ed: The immortal cells of Henrietta Lacks - Robin Bulleri

The video discusses the significance of HeLa cells, derived from Henrietta Lacks' tumor, which became the first immortal human cell line. These cells have been pivotal in scientific research, contributing to breakthroughs in cancer, virology, and genetics. Despite their importance, the ethical implications of using HeLa cells without consent are highlighted. HeLa cells have been used in various studies, including the development of the polio vaccine and understanding of HPV. Their unique properties, such as indefinite division, make them invaluable for research, although the exact reasons for their immortality remain unclear.
