The definition of HeLa cell is "Any of the cells of the first continuously cultured human carcinoma strain, originally obtained from cancerous cervical tissue and maintained for use in studying cellular processes."
From this, (and the fact that it's one of the choices on my homework) I assume it's cancer cells.
Good luck ^^
Continuous cell lines include HeLa cells derived from cervical cancer and CHO cells derived from Chinese hamster ovary. Primary cell lines are freshly isolated cells that have not been sub-cultured extensively, such as human primary keratinocytes isolated from skin tissue and primary rat hepatocytes isolated from liver tissue.
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 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.
it is an immortal cell
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.
Doctors harvested cells from Henrietta Lacks by taking a small tissue sample from her cervix without her consent during a medical procedure. The cells were then cultured in a laboratory setting by providing them with the necessary nutrients and environment to multiply and grow continuously, becoming the famous HeLa cell line.
Hela cell is about 14um each in size. Steven x
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 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.

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.
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.
