Movie 1

Cytoneme extension and retraction
Cytonemes from A compartment cells marked with membrane-tethered Cherry (ptc-Gal4 UAS-CD8:Cherry) orient towards the P compartment in the hinge region of this late 3rd instar wing disc. Their dynamic extension and retraction is recorded in this movie, which was taken at 12 second intervals in a 10 min period and is shown at 10 frames/second.
