Abstract
More than 40 years ago, studies of the Drosophila engrailed and Hox genes led to major discoveries that shaped the history of developmental biology. We learned that these genes define the state of determination of cells that populate particular spatially defined regions: the identity of segmental domains by Hox genes, and the identity of posterior developmental compartments by engrailed. Hence, the boundaries that delimit spatial domains depend on engrailed. Here, we review the engrailed field, which now includes orthologs in Drosophila and mouse, as well as many other animals. We focus on fly and mouse and highlight additional functions that span early stages of embryogenesis and neural development.
