HELA cells are one of the most famous and controversial cell lines in the history of science. They were derived from a cervical cancer patient named Henrietta Lacks in the 1950s without her knowledge or consent. Despite the ethical concerns surrounding their origin, HELA cells have been instrumental in numerous groundbreaking discoveries in biology, medicine, and genetics.

These immortal cells have been used in research on cancer, AIDS, genetic disorders, and the development of vaccines and medications. Their ability to divide indefinitely in culture has made them invaluable for studying cell behavior and testing experimental treatments.

However, the use of HELA cells has also raised ethical questions about patient rights, consent, and ownership of biological samples. Despite these controversies, HELA cells continue to be a vital tool in scientific research, highlighting the complex and sometimes problematic nature of advancing knowledge and technology in the field of biology.#3#
