Last week, HBO released the official trailer for 'The Immortal Life of Henrietta Lacks.' The movie, based on the 2010 best-selling book by Rebecca Skloot, premieres Saturday, April 22, at 8PM.

On March 15, Skloot announced, via Twitter, the release of the move trailer.

The movie stars Oprah Winfrey as Deborah Lacks, daughter of Henrietta Lacks, and Rose Byrne, as Skloot. 'The Immortal Life of Henrietta Lacks' tells the story of HeLa cells, which have been used in developing the polio vaccine, cloning, IVF, and more. Unfortunately, these cells were taken from a poor black woman with cancer named Henrietta Lacks without her permission in 1951.

While these cells have been bought and sold in laboratories worldwide and even blasted into space, Henrietta's children can't afford to pay for health insurance.

The book and movie deal with questions about ethics, race, and science as Henrietta's daughter, Deborah, learns how her mothers' cells contributed to research.

Skloot also tweeted that a movie-tie-in edition of the book was now available for purchase.

In November 2016, Skloot announced at the 2016 National AALAS Meeting that her next book would be about issues pertaining to animal research.
