This transcription factor is expressed in all brain neuromeres and functions as a columnar patterning gene in the early stages of cell differentiation. ''Vnd'' is important in cell development as well as cell maintenance during embryogenesis due to the expression of the gene in both the developing neural cells and the specified neuromeres. Knockout experiments of ''vnd'' reveal similar axonal defects as the knockout of the Hox gene ''labial (lab)''. Like the Hox genes, ''vnd'' is required for specification along the dorsoventral axis. Mutant ''vnd'' produce the loss of tritocerebral neural lineages as well as neuromeres, therefore this gene is crucial for the development of these cell lineages. Without proper ''vnd'' expression throughout Drosophila embryonic development, the brain would not become functional. == References == * Hirth F, Reichert H, Rijli F, Sprecher S, Technau G, Urbach R.
