Henrietta Lacks (born Loretta Pleasant; August 1, 1920 – October 4, 1951)[2] was an African-American woman[5] whose cancer cells are the source of the HeLa cell line, the first immortalized human cell line[B] and one of the most important cell lines in medical research. An immortalized cell line reproduces indefinitely under specific conditions, and the HeLa cell line continues to be a source of invaluable medical data to the present day.[7][8]
Well, probably.
