Fig. 2

Whole and local HE and TUNEL (green) staining results of the midgut in the PBS (CK) and BiotGm injection-treated groups at 0, 2, 4, 6, 8, and 10 h. Symbols: GL gut lumen, EC columnar epithelial cells, BM basement membrane, BC body cavity, bl epithelial blebbing. Intensive blebbing or sloughing of the epithelium onto the gut lumen was indicated by black arrows. All HE or TUNEL results were repeated at least twice using independently prepared samples with similar results. The complete DAPI- and TUNEL-stained midgut structure is shown in Supplementary Fig. 3. Scale bar: 100 μm, 50 μm.
