BMPs regulate msx gene expression in the dorsal neuroectoderm of Drosophila and vertebrates by distinct mechanisms.
In a broad variety of bilaterian species the trunk central nervous system (CNS) derives from three primary rows of neuroblasts.The fates of these neural progenitor cells are determined in part by three conserved transcription factors: vnd/nkx2.2, ind/gsh and whelen remote spotlight msh/msx in Drosophila melanogaster/vertebrates, which are expressed
