From: Dynamic Notch signalling regulates neural stem cell state progression in the Drosophila optic lobe
Notch signalling activation requires Neuralized function at the transition zone. (a-b”’) neur1 mutant clones stained for E(spl)mγ in green, (a,a”) Dpn in blue, (b,b”) L’sc in blue, (a”’) Dl in gray and (b”’) Asense (Ase), as a neuroblast marker, in gray. Clones were marked by the absence of RFP expression and dotted lines. (a-a”) Arrows show decrease in E(spl)mγ staining in PI progenitors and arrowheads in NBs. (b-b”) Arrows pointed L’sc-positive PII progenitor inside neur mutant clone. Scale bars are 20 μm
