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 ...

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.

Novartis and Viatris were hit with a federal lawsuit in Maryland on Monday by the family of a woman whose tissue cells were taken from her body in the 1950s and used to fuel medical research and ...

Recent research has proposed the idea that HeLa cells damaged with radiation (cells that are unique in that they have short-shouldered survival curves and two peaks of radio resistance during the cell cycle phase) show the fact that radio-suppression is mediated by intra-s checkpoints and reduces survival of cells in the s-phase.
For example, in epithelial cells, a special process called transcytosis allows some materials to enter one side of a cell and exit from the opposite side. Also, in some circumstances, late endosomes/MVBs fuse with the plasma membrane instead of with lysosomes, releasing the lumenal vesicles, now called exosomes , into the extracellular medium.
