In 1951, a woman died in Baltimore, U.S.A. She was called Henrietta Lacks. These are cells from her body. They were taken from her just before she died. They have been growing and multiplying ever since. There are now billions of these cells in laboratories around the world. If massed together, they would weigh 400 times her original weight. These cells have transformed modern medicine, but they also became caught up in the politics of our age.
