Hela cells and HEK293 cells are prominent in scientific research, each serving distinct purposes. Hela cells, established from cervical cancer tissue, are invaluable for studying cancer mechanisms and drug responses. They have been instrumental in vaccine development and understanding cell biology. Conversely, HEK293 cells, derived from human embryonic kidney tissue, are preferred for their ability to easily incorporate foreign DNA, making them ideal for gene expression and protein production. Delving into their unique characteristics helps researchers choose the ultimate cell line for their experiments, ensuring effective outcomes in diverse areas of biomedical research.
