The Role of HeLa Cells and HEK293 in Biomedical Research HeLa cells and HEK293 cells are two of the most widely used cell lines in biomedical research. HeLa cells, derived from cervical cancer, were the first human cells to be successfully cultured and have contributed significantly to cancer research, vaccine development, and gene mapping. HEK293 cells, originating from human embryonic kidney cells, are favored for their ability to easily transfect and produce proteins, making them essential in gene therapy and vaccine production. Together, these cell lines have revolutionized our understanding of cellular processes and are critical tools in advancing medical science and therapeutic innovations.
