neuralized is expressed in PII progenitors and in optic lobe neuroblasts. (a) Immunostaining of neur-lacZ larval brains for β-gal/neur in green, Dl in red and L’sc in blue. Arrowheads show PII progenitor expressing neur, Dl and L’sc. (b) Schematic representation of neur expression during the transition between NE cells into NBs. Scale bars are 20 μm
