Early life

During World War II, when he was about four and a half, Capecchi was separated from his family and for years fended for himself, sometimes living on the streets or in orphanages. His mother found him in a hospital in Reggio Emilia, and the family then emigrated to the United States to live with his uncle. University of Utah

He studied at Antioch College in Ohio and Harvard, where he earned his doctorate in 1967 under James Watson. DNA Learning Center

Gene targeting and knockout mice

In the early 1980s Capecchi found that DNA inserted into mammalian cell nuclei could be incorporated into the cell's genome. DNA Learning Center That work led to gene targeting in mouse embryo-derived stem cells, the method behind knockout mice, in which a chosen gene is switched off so researchers can study what it does. Nobel Prize

He has also studied the mouse Hox gene family, which helps direct how an embryo's body is laid out from head to tail. Wikipedia

Honors

Wikipedia lists, among others, the National Medal of Science (2001), the Kyoto Prize in Basic Sciences (1996), the Lasker Award for Basic Medical Research (2001, shared) and the Wolf Prize in Medicine (shared). He has been a Howard Hughes Medical Institute investigator since 1988. Wikipedia
