HeLa is a type of cell in an immortal cell line used in scientific research. It is the oldest and most commonly used human cell line. Its scientific name is Helacyton gartleri. It came from cervical cancer cells taken on February 8, 1951 from Henrietta Miss, who died of her cancer on October 4, 1951. Say no to plagiarism.

HeLa cells are called immortal because they can divide an unlimited number of times in a laboratory culture plate as long as the conditions for cell survival are met. There are many strains of HeLa cells because they continue to mutate in cell cultures, but all HeLa cells are descended from the same tumor cells extracted from Henrietta Lacks. The total number of HeLa cells that were released into the cell culture far exceeds the total number of cells that were in Henrietta Lack's body. HeLa cells grow quickly with the right nutrients, conditions and space. Indeed, HeLa cells are cancer cells that multiply and grow rapidly in an uncontrolled manner compared to normal cells. They can also spread and infect other cells. HeLa cells became cancerous due to infection with human papillomavirus 18. Cervical cancer is very closely associated with HPV 16 and HPV 18, which can disrupt the normal activity of the cell and make cells cancerous. However, not every woman who contracts one of these viruses will develop cervical cancer. In normal cells, cells can only divide by mitosis a certain number of times because the telomeres at the ends of chromosomes shorten with each division. This does not apply to many types of cancer cells, because they produce an enzyme called telomerase, which lengthens telomeres after chromosomes are copied and allows cells to continually multiply. Scientists have spent more time trying to keep cells alive than doing actual cancer research. cells. An infinite supply of HeLa cells freed up time for discovery. In 1952, the worst year of the polio epidemic, HeLa cells were used to test the vaccine that protected millions of people. Scientists have learned how to isolate a specific cell, multiply it, and create a cell line. Isolating a cell and keeping it alive is the basic technique of cloning and in vitro fertilization. Which is used to help people have children who are unable to do so.Keep in mind: This is just a sample.Get a custom paper now from our expert writers.Get a custom essayA scientist accidentally poured a chemical onto a HeLa cell that spread its chromosome tangles. Later, scientists used this technique to determine that humans have 46 chromosomes, or 23 pairs, not 48, which served as the basis for several types of genetic diagnoses. Lacks' cancer cells were found to use the enzyme telomerase to repair their DNA, allowing them and other types of cancer cells to function when normal cells would have died. Anticancer drugs that act against this enzyme are currently undergoing initial clinical trials..
