PATHOLOGY

Detailed explanation-1: -Since being discovered in the 1950s, experiments on HeLa cells have played a role in developing advances like the polio and COVID-19 vaccines, treatments for cancer, HIV, AIDS, and much more. About 55 million tons of these cells have been used in over 75, 000 scientific studies around the world.

Detailed explanation-2: -HeLa cells are used to study the potential treatment benefits of a drug called Hydroxyurea against certain blood cancers and sickle cell anemia. Scientists note that when Hydroxyurea is applied to cancerous cells, cancer growth slows down.

Detailed explanation-3: -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.

Detailed explanation-4: -They have been used to test the effects of radiation and poisons, to study the human genome, to learn more about how viruses work, and played a crucial role in the development of the polio and COVID-19 vaccines.

Detailed explanation-5: -The most significant issue with HeLa cells is how aggressively they can contaminate other cell cultures in a laboratory. Scientists don’t routinely test the purity of their cell lines, so HeLa had contaminated many in vitro lines (estimated 10 to 20 percent) before the problem was identified.
