Movie 3

Spermatids are released within the TE in Dlg1 knockdown testis: Time-lapse images of a ProtA-GFP/UAS-dsDlg1; PpY-Gal4>UAS-mCD8-RFP/+ depict retraction of an NB (green; arrow) from the HCC (red) even though the NB is not oriented away from the SV (arrowhead). As a result, the spermatids are released inside the testis.

Atypical septate junctions maintain the somatic enclosure around maturing spermatids and prevent premature sperm release in Drosophila testis
