When was the HeLa cell line cultured?
1951
Among the important scientific discoveries of the last century was the first immortal human cell line known as “HeLa” — a remarkably durable and prolific line of cells obtained during the treatment of Henrietta’s cancer by Johns Hopkins researcher Dr. George Gey in 1951.
How are cell lines cultured?
Cell culture refers to the removal of cells from an animal or plant and their subsequent growth in a favorable artificial environment. At this stage, the cells have to be subcultured (i.e., passaged) by transferring them to a new vessel with fresh growth medium to provide more room for continued growth.
Where did the HeLa cell line originated?
The HeLa cell line came from a cervical tissue sample from Lacks, a patient diagnosed and treated for terminal cervical cancer at The Johns Hopkins Hospital in Baltimore, Maryland, in 1951.
Why were HeLa cells a breakthrough in cell culturing?
Scientists discover that HeLa cells are found to be an effective tool for growing large amounts of poliovirus, the cause of Poliomyelitis, or polio disease. The high amount of virus that can be grown in HeLa cells allow scientists to better understand how the virus infects cells and causes disease.
Are there other immortal cells besides HeLa?
There are various immortal cell lines. Some of them are normal cell lines (e.g. derived from stem cells). Other immortalised cell lines are the in vitro equivalent of cancerous cells. The origins of some immortal cell lines, for example HeLa human cells, are from naturally occurring cancers.
What happened to HeLa cells that Mary cultured?
What happened to the HeLa cells that Mary cultured? The cells survived and grew with mythological intensity. Gey chose to give away samples of HeLa to his colleagues almost immediately.
How are cell cultures obtained?
In primary cell culture, cells obtained from such parental tissues (living tissues) as the liver and kidney, are introduced into suitable media for growth. Once the cells have been obtained, they can either be cultured as explants culture, suspension or monolayer. These cells are refers to as continuous cell lines.
What is the nature of HeLa cell lines?
The HeLa cell line was derived for use in cancer research. These cells proliferate abnormally rapidly, even compared to other cancer cells. Like many other cancer cells, HeLa cells have an active version of telomerase during cell division, which copies telomeres over and over again.
How did HeLa cells help HPV?
In Lacks’s case, the virus entered the cells and turned off the gene that would normally have suppressed the formation of tumors. Years later, scientists used that knowledge to develop HPV vaccines, which are now widely available and credited with reducing cases of HPV infection in teenage girls by almost two-thirds.
Are Henrietta Lacks cells still alive today?
These cells were then cultured by George Otto Gey, who created the cell line known as HeLa, which is still used for medical research. As was then the practice, no consent was required to culture the cells obtained from Lacks’s treatment….

What are HeLa cells and why they are important?
Key Takeaways: HeLa Cells HeLa cells are the first immortal human cell line. The cells came from a cervical cancer sample obtained from Henrietta Lack in 1951, without her knowledge or permission. HeLa cells have led to many important scientific discoveries, yet there are disadvantages to working with them.
Are HeLa cells still used?
Yes.HeLa cells are still used in medical research . These are an immortal cell line which show the synthesis of an active telomerase ,which prevents the chromosome from shortening.
What have HeLa cells accomplished?
The cells were called HeLa cells. Descendents of Henrietta’s cells helped zero in on the virus that caused polio, which ultimately led to the development of polio vaccines. This immortal cell line has been used to test the effects of medications and to try to identify the causes of cancers.
What did HeLa cells accomplish?
HeLa cells have also been employed to help standardize procedures and tools for culturing and growing cells. When Dr. Gey first started sharing the cells, he had to use couriers to transport them via airplane, and there was a very limited timeframe in which the cells would survive.
