(L), Diap1 is monitored by the GFP.4.3. (green) reporter (Djiane et al., 2013; Zhang et al., 2008). Diap1-GFP is detected in a subset of adult midgut esg+ cells that are negative for the mitotic marker PH3 (red, inset) and for EE marker Prospero (Pros, grey in inset). Diap1-GFP is not detected in mature EC (large nuclei cells, DAPI in blue). Data information: Scale bars, 50µm.
