The original cells came from a visible malignant cervical tumor in the body of a 31-year-old African American woman named Henrietta Lacks. HeLa cells are a common source of cross-contamination of other cell lines and a suspected cause of numerous instances of cell line misidentification. The HeLa cell genome has also been shown to be highly unstable, housing numerous genomic rearrangements e. Cytogenetics HeLa cells are hypertriploid and have a modal chromosome number of 82, with four copies of chromosome 12 and three copies of chromosomes 6, 8, and 17.

Origins of the HeLa Cell Line The HeLa cell line is an immortal cancer cell line. Figure: Fluorescent light micrograph HeLa cervical cancer cell with actin green , tubulin red , nucleus blue. HeLa cells are a common source of cross-contamination of other cell lines and a suspected cause of numerous instances of cell line misidentification.

In fact, citing their ability to replicate, the disparity between human and HeLa cells, and their ability to proliferate unchecked despite human attempts to contain them, some scientists have described HeLa as its own species, and a highly successful one, at that. This information should not be considered complete, up to date, and is not intended to be used in HELA of a visit, consultation, or advice of a legal, medical, or any other professional. The uncontrolled growth of HeLa is such a problem in many labs that if the lab wants to use HeLa cells it cannot use any other cell line in fear of compromising good science.

Origins of the HeLa Cell Line The HeLa cell line is an immortal cancer cell line. The original cells came from a visible malignant cervical tumor in the body of a 31-year-old African American woman named Henrietta Lacks. The cells were taken in 1951 and given to Dr. George Gey, who produced the original cell line. Henrietta Lacks died the same year, in October, from the very cancer cells that have since been used in science to save thousands of lives.

They are so durable, in fact, that in 1974, a researcher named Walter Nelson-Rees suggested that all cell cultures have been contaminated with HeLa. Although not all cells were contaminated, it became evident that many of the cells in labs around the world were contaminated. The uncontrolled growth of HeLa is such a problem in many labs that if the lab wants to use HeLa cells it cannot use any other cell line in fear of compromising good science. It has been demonstrated that 10-20% of existent cell lines have been infiltrated by HeLa. HeLa cell doubling time is 24 hours, and, years later, they are still some of the strongest cells known to science. In fact, citing their ability to replicate, the disparity between human and HeLa cells, and their ability to proliferate unchecked despite human attempts to contain them, some scientists have described HeLa as its own species, and a highly successful one, at that. Controversy Surrounding HeLa The HeLa cell line sparked a 1950s debate on medical ethics because the HeLa cells were propagated, and later commercialized to a great extent, without the knowledge or permission of Lacks or her family. Cytogenetics HeLa cells are hypertriploid and have a modal chromosome number of 82, with four copies of chromosome 12 and three copies of chromosomes 6, 8, and 17. The modal number ranges from 70 to 164.
