How did HeLa cells advance biomedical research?
HeLa cells are used by scientists to develop a cancer research method that tests whether a cell line is cancerous or not.
This method proves so reliable that scientists use it to this day.
HeLa cells are taken aboard some of the very first capsules used to explore outer space..
How did HeLa cells contaminate?
Unfortunately, HeLa cells have been contaminating other cell cultures for decades.
Due to, for instance, carelessness in the lab these rapidly reproducing cells began taking over other cell cultures.
This wasn't limited to HeLa alone, but was also observed in other immortal cell lines..

This wasn't limited to HeLa alone, but was also observed in other immortal cell lines..
How have HeLa cells saved lives?
In addition to HPV, the cells have aided in the production of the polio vaccine and contributed to advancements in cancer, AIDS and Parkinson's treatments and the development of the recent coronavirus vaccines.
In total it's estimated that HeLa cells have saved over 10 million lives..
What biosafety level is HeLa cells?
Biosafety Level 2 (BSL-2) protections apply to work with pathogens or infectious organisms associated with human diseases.
These organisms pose a moderate health hazard.
Centers for Disease Control and Prevention (CDC) guidelines (pdf) require BSL-2 containment for work with HeLa cell lines..
What does HeLa stand for?
HeLa Cells: A Lasting Contribution to Biomedical Research
Some of her cancer cells began being used in research due to their unique ability to continuously grow and divide in the laboratory.
These so-called “immortal” cells were later named “HeLa” after the first two letters of Henrietta Lacks first and last name..
What is HeLa cell type?
HeLa cells are the first immortal human cells to be grown in culture and the basis for countless significant scientific discoveries.
They were isolated in 1951 from a cervical carcinoma derived from a 31-year-old patient..
What is the HeLa epithelial cell line?
HeLa cells are an immortal human epithelial cell line derived from a cancerous tumour of the cervix (adenocarcinoma).
It was established in 1951 from a biopsy taken from Henrietta Lacks, and was the first human cell line to survive and grow in the laboratory..
What risk group are HeLa cells?
: The human cell lines HEK293, HEK293T and HeLa cells are classified as risk group 2.
They are known to contain viral DNA from viruses that are pathogenic to humans..
Where is the HeLa cell located?
The HeLa cell line was the first immortal human cell line that George Otto Gey, Margaret Gey, and Mary Kucibek first isolated from Henrietta Lacks and developed at The Johns Hopkins Hospital in Baltimore, Maryland, in 1951..
Why should HeLa cells be used for scientific research?
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.
This knowledge lays important groundwork for the eventual development of the polio vaccine..
Why should we keep using HeLa cells?
Over the past several decades, this cell line has contributed to many medical breakthroughs, from research on the effects of zero gravity in outer space and the development of polio and COVID-19 vaccines, to the study of leukemia, the AIDS virus and cancer worldwide..
- HeLa cells, like many tumours, have error-filled genomes, with one or more copies of many chromosomes: a normal cell contains 46 chromosomes whereas HeLa cells contain 76 to 80 (ref) total chromosomes, some of which are heavily mutated (22-25), per cell.
- HeLa Cells: A Lasting Contribution to Biomedical Research
Some of her cancer cells began being used in research due to their unique ability to continuously grow and divide in the laboratory.
These so-called “immortal” cells were later named “HeLa” after the first two letters of Henrietta Lacks first and last name. - Tip 1: To count HeLa cells without staining, use either the predefined setting “CellsA” in SoftMax Pro Software or create a new setting using the drawing tools in the software.
The analysis method you use will depend on your cells' morphology and growth conditions. - Working with Human Tissues and Cells
All unfixed human tissue and cells are to be assumed to be infectious (the concept of “Universal Precautions”) and must be handled using Biosafety Level 2 (BSL-2) practices and procedures.
