Homology of insect corpora allata and vertebrate adenohypophysis?

► Corpora allata, adenohypophysis and cells within share features indicating homology. ► We identify correspondencies by comparing recent findings about the two organs. ► We show that corpora allata and adenohypophysis fulfill several homology criteria. ► Cells express similar proteins, are regulated by RFamides and produce nitric oxide. ► Their development might be initiated by Six3 and Pitx.
