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 ...

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 1991, he proposed that HeLa cells be defined as a new species, which was named Helacyton gartleri. [2] Van Valen originated the concept of fuzzy sets, prior to the formalization of this concept by L.A. Zadeh. [3] He was the editor of the journal Evolutionary Theory, which he printed on simple paper stock under the motto, "Substance over form."
