HeLa cells, an immortalized cell line
Frequently, scientists try to understand how the cells in our body behave by culturing them in a dish. But normal cells eventually stop dividing and die, so studying cells that can grow “forever” has become an invaluable tool in scientific research. These are HeLa cells, the first immortalized cell line ever established by scientists. HeLa cells are cervical cancer cells that were surgically removed in the 1940s from an African-American woman, Henrietta Lacks (whose story was recently documented by Rebecca Skloot in The Immortal Life of Henrietta Lacks). Since the establishment of HeLa, thousands of immortalized cell types have been developed, but HeLa cells remain the most commonly used one.

Human cortical neural stem cells
Cortical neurons are located in the cerebral cortex of the brain, a region responsible for memory, thought, language, and consciousness. Neural stem cells are “immature” cells committed to become neurons and helper cells of the brain. Neurons are the liaison between our brain and the world. When we eat a lemon, neurons connected to our taste buds tell the brain that it’s sour. Messages from the brain can also be sent elsewhere, as when neurons command muscles to contract while lifting a heavy object.
