A good summary of Henrietta Lacks's story can be found in the article "Henrietta's Dance." Rebecca Skloot wrote this article for Johns Hopkins Magazine in 2000, ten years before the publication of The Immortal Life of Henrietta Lacks.
In 2013, three years after the publication of The Immortal Life of Henrietta Lacks, scientists succesfully sequenced the genome of the HeLa cell and published the entire genome online. They did not ask permission from the Lacks family. After months of discussion, the Lacks family agreed to a deal that would allow limited use of the HeLa genome while still maintaining their genetic privacy.
In Chapter 33 of The Immortal Life of Henrietta Lacks, Deborah Lacks and Rebecca Skloot visit Crownsville State Hospital, the former Hospital for the Negro Insane, where Elsie Lacks was held until her death.
