Delta necessary ans sufficient for Notch signalling inducing PI progenitor formation. (a-b”) Immunostaining of Dl misexpressing clones, E(spl)mγ in green, and Dpn in red. Clones were marked by β-gal staining in blue and dotted line. Arrowheads show E(spl)mγ activation in clone neighbouring cells. (c-d”’) Dlrev10 mutant clones stained for E(spl)mγ in green, Dpn in blue, and Dl in gray. Clones were marked by the absence of RFP expression and dotted lines. Arrows show E(spl)mγ expression inside mutant cells that were in contact with wild-type cells. Arrowheads show NBs not expressing E(spl)mγ. Scale bars are 20 μm
