The main advantage of using an immortal cell line for research is its immortality; the cells can be grown indefinitely in culture. This simplifies analysis of the biology of cells which may otherwise have a limited lifetime.

Why are immortalized cell lines important for scientific research?
Immortalized cell lines of neuronal origin can be used to study properties unique to neurons. Scientists have used neuronal cell lines to investigate processes that occur during differentiation in neurons, such as axon selection, guidance, and growth.
Why are cell lines so valuable to medical research?
Cell lines are in vitro model systems that are widely used in different fields of medical research, especially basic cancer research and drug discovery. Their usefulness is primarily linked to their ability to provide an indefinite source of biological material for experimental purposes.
Which cell line uses biological research?
Immortal cell lines are often used in research in place of primary cells. They offer several advantages, such as they are cost effective, easy to use, provide an unlimited supply of material and bypass ethical concerns associated with the use of animal and human tissue.
Why are HeLa cells so important?
HeLa cells have been used to test the effects of radiation, cosmetics, toxins, and other chemicals on human cells. They have been instrumental in gene mapping and studying human diseases, especially cancer. HeLa cells were used to maintain a culture of polio virus in human cells.
Why are immortal cell lines important for biological research quizlet?
Why are immortal cell lines important for biological research? They can replicate indefinitely and do not experience natural cell death.
Why are immortal cell lines important?
Immortal cell lines are a powerful tool for the biological investigator to research the biochemistry and cell biology of multicellular organisms, which plays an important role in the study of the biology of cell growth, differentiation, and senescence.
What makes a cell line immortal?
An immortalised cell line is a population of cells from a multicellular organism which would normally not proliferate indefinitely but, due to mutation, have evaded normal cellular senescence and instead can keep undergoing division. The cells can therefore be grown for prolonged periods in vitro.
What made Henrietta’s cells immortal?
Lacks’ cancer was a uniquely aggressive case, and her biopsy sample doubled in volume every 20 to 24 hours where other cultures would normally die out. If they were fed the right mixture of nutrients to allow them to grow, the cells were effectively immortal.
What is a cell line in biology?
Cell Line. A cell line is a permanently established cell culture that will proliferate indefinitely given appropriate fresh medium and space. Lines differ from cell strains in that they become immortalized.
What kind of impact have cells made in biomedical research?
In particular, HeLa cells have helped scientists better understand a variety of viral infections. Researchers infect cells with a virus like measles or mumps and observe how it affects them. Researchers have also been able to develop vaccines for infections such as polio and human papillomavirus (HPV).
Which cell line used in biological research is also the name of Marvel’s goddess of death?
Henrietta Lacks (born Loretta Pleasant; August 1, 1920 – October 4, 1951) was an African-American woman whose cancer cells are the source of the HeLa cell line, the first immortalized human cell line and one of the most important cell lines in medical research.
How do cell lines differ from primary cells?
Primary cell culture is the culture of cells directly isolated from parental tissue of interest; whereas cell line is the culture of cells originated from a primary cell culture, which is generally used to expand cell population and prolong life span. However, cell lines have prolonged lifespan.
Why is Henrietta Lacks called immortal?
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 special about Henrietta Lacks cells?
Lacks’ cells doubled every 20 to 24 hours. Today, these incredible cells— nicknamed “HeLa” cells, from the first two letters of her first and last names — are used to study the effects of toxins, drugs, hormones and viruses on the growth of cancer cells without experimenting on humans.
Why are HeLa cells important to research on polio and other medical conditions?
Eradicating polio At the time of Lacks’s death, polio was one of the world’s most devastating viral diseases. HeLa cells helped make the vaccine available sooner. Not only were these cells more susceptible to the virus than the cells scientists previously used, the fast-growing cells were nearly impossible to kill.
