Expression patterns of DBHD-res.

The expression of DBHD-res was detected by the EGFP staining (green). Genotype in all panels: DBHD-res; DBHD^−/−. (A) Larval fat body. (B) Larval salivary gland. (C) eye-antennal disc. (D) Magnified view of eye disc. (E) Larval brain. (F) Ring glands. (G) Epithelium of larval midgut. (H) Epithelium of adult midgut. (I) Magnified view of adult midgut. (J) Testis. (K) Germarium. (L) Egg follicles. Arm (red) marks the cell borders; Prospero (Pros, red, in nuclei) marks the intestinal EE cells; Dpn marks the neuroblasts in the brains; DAPI (blue) marks the nuclei in G–I, L. Note the DBHD-res was also expressed in some EC cells in the gut (E–G, marked by the DAPI-labeled polyploid cells).
