HeLa cells have changed the field of medicine and have led to multitudes of life saving innovations. Unfortunately, the donor, Henrietta Lacks, did not consent to the harvesting of the cell line, and until now, her and her family have not received compensation from companies that profited from products tested and designed with the HeLa cell line. Her family reached a settlement with the company that maintains the cell line for the industry.
I actually just learned of her earlier this year. If you want more info then check out these two Youtube vids which goes more into her life and why these cells are so important. They also explain the controversy behind the acquisition and use of these cells. https://www.youtube.com/watch?v=WU5uCiV0MyQ & https://www.youtube.com/watch?v=22lGbAVWhro
