HELA cells are arguably one of the most famous and controversial cell lines in scientific history. These cells were obtained from a cancerous tumor on the cervix of Henrietta Lacks in 1951 without her knowledge or consent. Despite this ethical dilemma, HELA cells have proved to be invaluable in research, as they are able to divide indefinitely in culture, creating an immortal cell line.

These cells have been used in countless experiments and studies, ranging from the development of vaccines to understanding the mechanisms of cancer. The unique properties of HELA cells have enabled researchers to make groundbreaking discoveries in cell biology, genetics, and medicine.

Although the story of Henrietta Lacks and the HELA cells is a complex and controversial one, there is no denying the impact they have had on the scientific community. Through their contributions to research, HELA cells have helped save countless lives and continue to play a pivotal role in advancing our understanding of human biology.#3#
