Expression of comm2 during D. melanogaster nerve cord development. comm2 expression is detected during D. melanogaster embryonic ventral nerve cord development. High levels of transcript are detected at Stage 13 (A) and are observed in a more restricted set of neurons at Stage 15 (B). By stage 17 (C), when most commissural axons have crossed the midline, expression in the nerve cord has significantly diminished. Arrowheads in A–C mark the midline; filleted nerve cords are oriented anterior upward in these panels.
