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 ...

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 or ...
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.

In cell biology, a paraspeckle is an irregularly shaped compartment of the cell, approximately 0.2-1 μm in size, [1] found in the nucleus' interchromatin space. [2] First documented in HeLa cells, where there are generally 10-30 per nucleus, [ 3 ] Paraspeckles are now known to also exist in all human primary cells , transformed cell lines and ...
In HeLa cells in vitro, the force generated by a half-deformed mitotic cell is on the order of 50 to 100 nanonewtons. [10] [11] Internal hydrostatic pressure has been measured to increase from below 100 pascals in interphase to 3 to 10 fold that in mitosis. [10] [11] [15]
