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.
Speaking in strictly technical terms, Henrietta must weigh more than a house by now.
Around 55 million tons of HeLa cells have been cultured. So, yeah, more than a house.
