Detailed explanation-1: -Scientists use HeLa cells to discover how the presence of the Human Papilloma Virus (HPV) can lead to certain types of cervical cancer. The discovery that HPV can lead to cervical cancer paves the way for development of one of the first anti-cancer vaccines.
Detailed explanation-2: -So what makes HeLa special? As cancer cells, HeLa cells are unlike normal human cells, and there is no better proof of this than to take a look at its chromosomes, or karyotype. Normal human cells have 46 chromosomes, while HeLa has 76 to 80 heavily mutated chromosomes.
Detailed explanation-3: -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.
Detailed explanation-4: -In the article “HeLa Cells 50 Years On: The Good, The Bad, and The Ugly, ” Masters describes that, despite the benefits of the HeLa cell line, it has caused significant negative impacts on research due to its propensity to contaminate other cell lines, which can potentially invalidate research findings.
