Transmission electron microscopy analysis of rescue nephrocytes. a–h Garland nephrocytes expressing Crb–RNAi and the indicated rescue transgene were analyzed by electron microscopy. i Amount of nephrocyte diaphragms (NDs) per µm surface area (basal membrane) was quantified. At least three nephrocytes from different individuals were scored. j, k Schematic representation of Crb-deletion constructs and mutations used in this study. Graphic symbols used are explained in Fig. 1a
