... in determining neuronal subtype identity in flies and vertebrates. dbx belongs to the highly divergent H2.0 family of homeobox genes. In vertebrates, Dbx1 and Dbx2 promote the development of a subset of interneurons, some of which help mediate left-right coordination of locomotor activity. Here, we identify...

... the dorsoventral midline. Dbx-derived oligodendrocytes comprise less than 5% of the total; they are formed late during embryogenesis by transformation of radial glia and settle mainly in the lateral white matter. Development of Dbx-derived oligodendrocytes in vitro can occur independently of Shh but requires FGF...
