Aron Arthur Moscona, a developmental biologist who taught at the University of Chicago, has died at the age of 87. Moscana's work in the late 1950s to the early 1970s determined how cells in the developing embryo find each other and interact. His work led to the discovery of cadherins, cell surface molecules that allow cells to recognize and interact with one another. "It allowed other scientists ... to explore the processes by which blood cells leave the bone marrow to circulate, sperm and eggs free themselves, and skin cells cross gaps to close a wound," says an article in the New York Times.
