…cells from Lacks's cancerous cervical tumor were taken without her knowledge, which was common practice in the United States at the time. Cell biologist George Otto Gey found that they could be kept alive, and developed a cell line. Previously, cells cultured from other human cells would survive for only a few days…

Scanning electron micrograph of cultured HeLa cells infected with adenovirus, taken in 1976. These cells were originally from Henrietta Lacks and were first grown in the laboratory of Dr Gey in 1951. A light micrograph (x130) of the same cells (inset) reveals rounded double cells in the center, in the process of dividing.
