If HeLa cells are cancer cells, how are they useful for research into anything other than cancer, like vaccine production?
Since the 50s, if researchers wanted to figure out how cells behaved in a certain environment, or reacted to a specific chemical, or produced a certain protein, they’ve turn to HeLa cells. They did that because, despite being cancerous, HeLa still shared many basic characteristics with normal cells: They produced proteins and communicated with one another like normal cells, they divided and generated energy, they expressed genes and regulated them, and they were susceptible to infections, which made them an optimal tool for synthesizing and studying any number of things in culture, including bacteria, hormones, proteins, and especially viruses. Viruses reproduce by injecting bits of their genetic material into a living cell, essentially reprogramming the cell so it reproduces the virus instead of itself. When it came to growing viruses–as with many other things–the fact that HeLa was malignant just made it more useful. HeLa cells grew much faster than normal cells, and therefore produc
