G. Representative image of a Drosophila Dronc heterozygous intestines 7 days after transfer to 29 oC. esg expression in green (GFP) labels all intestinal progenitors cells, whilst Su(H)-lacZ (red) distinguishes a subpopulation of EBs within the esg-expressing cells. Genotype: w1118, Su(H)GBE-LacZ; esg-Gal4 UAS-CD8-GFP / + ; TubG80ts UAS-Histone-RFP DroncKO / +
