From: Merlin is required for coordinating proliferation of two stem cell lineages in the Drosophila testis
Mer is required for stability of adherens junction between CCs. (A–C) Apical tip of a wild-type (A and B) and Mer ts1 mutant (C) testis stained for E-cadherin (Blue), Vasa (Green), and Add (Red). GSCs are indicated by white dots. Hub (*). Bar, 10 µm. (D and E) Apical tip of wild-type (D) and Mer ts1 mutant (E) testis visualized for Arm-GFP (Green), Vasa (Blue), and Add (Red). (F and G) Transmission electron microscopy showing junctions between two somatic cells in a wild-type (F) and Mer ts1 (G) testis. Arrows indicate cell-cell junctions. Blue, double-headed arrows in (F) indicate gaps in cell-cell junction structure. We noted that Mer ts1 mutant somatic cells have numerous multilamellar bodies (yellow arrowhead), although its meaning is currently unclear. Bar, 500 nm.
