She died in 1951. But cells taken from her body are still alive tonight — dividing in labs on every continent.
This is the story of Henrietta Lacks, the woman behind HeLa cells: the first human cells scientists could grow indefinitely outside the body. They helped test the polio vaccine, advance IVF, map human genes, study radiation and spaceflight, and contribute to research behind modern vaccines.
But the breakthrough came from two small samples taken during cancer treatment without her knowledge or consent. Her family was not told for decades, even as an entire scientific industry grew around cells labeled with four letters: HeLa.
In this video, we follow the science of why normal cells die, how Henrietta’s cancer cells broke that rule, why HeLa became one of the most important tools in medical history, and how the ethical questions around consent, credit, and profit still matter today.

The professor "cultivated" the experimental samples in the college biology lab. At that time, one cell cost the schools $25 from laboratory supply companies.
+1: if doctors got a cancer tissue sample from a person suffering the same type of cancer, won't that act the same way as the HeLa sample? So why won't we start fresh with a new person's sample that has not a 70-years' history of mutations?
