HeLa
HeLa
HeLa (/hiːˈlɑː/) is a cell type in an immortal cell line used in scientific research. It is the oldest and most commonly used human cell line. The line was derived from cervical cancer cells taken from Henrietta Lacks, a patient who died of cancer in 1951.
Etymology
The name "HeLa" was derived from the name of the patient, Henrietta Lacks. The first two letters of her first and last names were combined to create the term.
History
The HeLa cell line was first derived by George Otto Gey in 1951. The cells were taken from a biopsy of a cervical tumor taken from Henrietta Lacks, who later died from her cancer that same year. The cells were notable for their ability to multiply indefinitely in a laboratory setting, a trait which was previously unheard of. This made them invaluable for medical and biological research.
Use in Research
HeLa cells have been used in various types of research, including cancer research, virology, and even space biology. They have been instrumental in many scientific breakthroughs, such as the development of the polio vaccine.
Controversy
The use of HeLa cells has been the subject of ethical controversy, as they were taken without Lacks' knowledge or consent. This has led to discussions about the rights of patients and the use of their biological materials in research.
