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 ...
Immortal cell lines are a very important tool for research into the biochemistry and cell biology of multicellular organisms. Immortalised cell lines have also found uses in biotechnology . An immortalised cell line should not be confused with stem cells , which can also divide indefinitely, but form a normal part of the development of a ...
As a cancer researcher who uses HeLa cells in my everyday work, even I sometimes find it hard to believe. ... On Aug. 1, 2023, over 70 years after doctors took Lacks’ cells without her consent ...

One enzyme plays a key role in how tumor cells replicate and divide indefinitely. Identifying the genes that give these cells their immortality could provide new drug targets to treat cancer.
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.
Among the most commonly used cell lines are HeLa and Jurkat, both of which are immortalized cancer cell lines. [4] These cells have been and still are widely used in biological research such as creation of the polio vaccine, [5] sex hormone steroid research, [6] and cell metabolism. [7] Embryonic stem cells and germ cells have also been ...
The estate of Henrietta Lacks filed a lawsuit in Maryland federal court on Thursday accusing biopharmaceutical company Ultragenyx Pharmaceutical of unlawfully profiting from cells that were taken ...
