Development of the Drosophila olfactory sense organs utilizes cell-cell interactions as well as lineage (original) (raw)

Development of the Drosophila olfactory sense organs involves both lineage and cell-cell interactions, diverging from the mechanisms used in other sensory organs. This study identifies that various sensilla types on the Drosophila antenna display distinct developmental pathways and not solely reliant on the achaete-scute complex genes. The mechanisms include regulation by Notch signaling and suggest further unidentified proneural genes are likely involved in the specification of the different sensory cells.
