Movie showing movement of PA-GFP through the RCs in a spermatids lacking a fusome. Photoactivation of PA-GFP in a subset of spermatids in bam-Gal4>Spectrin RNAi testes demonstrates intercellular exchange of PA-GFP is not mediated by the fusome post-meiotically. Images were acquired at 30 second intervals for 40 minutes following activation.
