HeLa cells, derived from Henrietta Lacks without her consent in the 1950s, raise significant ethical concerns regarding informed consent and exploitation. While they have contributed immensely to medical research, the lack of permission from Lacks and her family highlights issues of racial inequity and the rights of patients. Today, the case underscores the importance of ethical standards in research, including transparency and consent. Thus, while HeLa cells themselves are a valuable scientific resource, their origin is considered an unethical practice by modern standards.
HeLa cells are known to have a triploid karyotype, which means they have three sets of chromosomes instead of the usual two sets found in diploid cells. This results in HeLa cells having around 69-82 chromosomes.
HeLa cells were used by Jonas Salk to test the first polio vaccine in the 1950's. Since that time HeLa cells have been used for "research into cancer, AIDS, the effects of radiation and toxic substances, gene mapping, and countless other scientific pursuits". According to author Rebecca Skloot, by 2009, "more than 60,000 scientific articles had been published about research done on HeLa, and that number was increasing steadily at a rate of more than 300 papers each month.
HeLa cells have been used in research to study cell biology, cancer, virology, and genetics. These cells have been instrumental in advancing our understanding of diseases and developing new treatments and therapies.
HeLa cells were remarkable because they were the first human cells to be successfully cultured and grown indefinitely in a laboratory setting. They have been used in countless scientific discoveries and medical breakthroughs due to their ability to divide rapidly and be easily manipulated. Henrietta Lacks, the woman from whom the cells were taken without her knowledge or consent, has since become a symbol of ethical issues surrounding informed consent in medical research.
That cross-contaminations of HeLa are still a major ongoing problem with modern cell cultures not with your cells, exactly. If you have had a transplant of tissues that involve HeLa cell lines, you will not see these on your skin.
No, HeLa cells should not be considered a new species. HeLa cells are a human cell line derived from cervical cancer cells, so they are still classified as human cells.
HeLa cells are a line of immortalized human cells that have been widely used in scientific research. They were the first human cells to be successfully grown in a laboratory and have been pivotal in advancing fields such as cell biology and medicine. They were named after Henrietta Lacks, the woman from whom the cells were originally taken without her knowledge or consent in 1951.

Research has shown that HeLa cells have an active form of the enzyme Telomerase (not present in normal cells, but can be found in most cancerous cells). Telomerase is active during cell division, and prevents the shortening of telomeres - a mechanism that is associated with ageing and eventual cell death.

Well, Hela cells are basically immortal cell line . They will keep growing if they are provided with appropriate media (e.g DMEM,10 % FCS/FBS & antibiotic). Moreover , you should also check for the cellular confluence, if its higher than 90 % then your cells start to die and you need to harvest them again.
