Federal records confirm that Henrietta Lacks' cells (HeLa) were used to develop the polio vaccine, chemotherapy, and gene mapping. Similarly, the HEK-293 cell line, derived from an unborn child in the Netherlands in 1973, is ubiquitous in modern medicine and processed foods. These immortal cell lines have reproduced indefinitely in labs, with the total mass of HeLa cells produced estimated to outweigh 100 Empire State Buildings.
