You may have learned of the line of cells known as the HeLa strain in a biology class, where a teacher explained the "virtually immortal" nature of these rapidly multiplying cells, and how they played a defining role in science. Over the last six decades, the prolific HeLa cells have been used to develop the first polio vaccines, test chemotherapy drugs, and develop techniques for in vitro fertilization. With their amazing capacity to multiply, the cells are an endless bounty to scientists.

HeLa has helped build thousands of careers, not to mention more than 60,000 scientific studies, with nearly 10 more being published every day, revealing the secrets of everything from aging and cancer to mosquito mating and the cellular effects of working in sewers [The New York Times].
