HeLa cells are rapidly dividing cancer cells, and the number of chromosomes varies during cancer formation and cell culture. The current estimate (excluding very tiny fragments) is a "hypertriploid chromosome number (3n+)", which means 76 to 80 total chromosomes (rather than the normal diploid number of 46) with 22–25 clonally abnormal ...

The origins of some immortal cell lines – for example, HeLa human cells – are from naturally occurring cancers. HeLa, the first immortal human cell line on record to be successfully isolated and proliferated by a laboratory, was taken from Henrietta Lacks in 1951 at Johns Hopkins Hospital in Baltimore, Maryland.

The book is about Henrietta Lacks and the immortal cell line, known as HeLa, that came from Lacks's cervical cancer cells in 1951. Skloot became interested in Lacks after a biology teacher referenced her but knew little about her. Skloot began conducting extensive research on her and worked with Lacks' family to create the book.
If a cell line is thought to be contaminated, it is usually tested for authenticity. [b] The widespread contamination of HeLa cells was initially recognized by Walter Nelson-Rees using simple Giemsa stain karyotyping under a light microscope. This technique works well in recognizing HeLa because these cells have distinctive chromosome aberrations.
The Immortal Life of Henrietta Lacks is a drama television film directed by George C. Wolfe and starring Oprah Winfrey and Rose Byrne.It is based on the book of the same name by Rebecca Skloot and documents the story of Henrietta Lacks, who was diagnosed with cervical cancer in the 1950s, and whose cancer cells (later known as HeLa) would change the course of cancer treatment.
By the time Gey published a short abstract claiming some credit for the development of the line, the cells were already being used by scientists all over the world. [5] Due to the unusual growth capabilities of the HeLa cell line, it also contaminated many cell cultures and ruined years of research, as discovered by Stanley Gartler in 1966. [3]
The cells, later known as HeLa cells, grew at an astonishing rate in the lab and were shipped and sold to researchers for various purposes. Research with the cells helped to facilitate medical breakthroughs, including the vaccines for polio and human papillomavirus , though controversy later arose because the cells were being used without the ...
