A. ReDDM activation in Dronc heterozygous (+/-) intestine 7 days after temperature shift at 29 Co; esg expression (green) labels the intestinal progenitor cells, Histone-RFP (red) is a semi-permanent marker retained in differentiated cells and Pdm-1 (grey) labels differentiated ECs. The red arrows indicates the enlarged areas depicted in the insets in the entire figure. DAPI labels the DNA In the entire Figure (blue). All of the experiments in the entire figure have been made under experimental conditions that protect the epithelial integrity (intestine reared in Oxford Medium and flies transferred every two days into vials with fresh food).
