Post-meiotic Drosophila spermatogenesis. (A) Schematic representation of spermatogenesis highlighting round and individualizing spermatids. (B) Fluorescent images of spermatids co-expressing Arl1-mCherry (acroblast, red), GFP-PACT (basal body, green) and Histone-GFP (nucleus, green). (C) Confocal images of elongated cysts with antibody staining of the cis-Golgi marker GM130 (red) localizing at the basal end of the cysts. (D) Fluorescent images of Snky-GFP (green) in elongated 64-cell cysts marking the formed acrosome. Nuclei labelled with DAPI (blue) in C,D. Scale bars: 10 µm in B-D.
