Fig. 2. In situ hybridisation reveals epithelial expression of CG10806 and CG31052. (A) CG10806 anti-sense showing strong expression in the hindgut (HG) and weaker expression in the Malpighian tubules (MT), with weak staining in the midgut (MG). (B) CG31052 anti-sense showing expression in both the hindgut and the Malpighian tubules, with no staining in the midgut. (C,D) Negative controls; sense probes for CG10806 (C) and CG31052 (D) show no staining.
