Live-imaging of wild-type embryonic renal tubule morphogenesis
Time-lapse in vivo imaging of embryonic (anterior) renal tubule morphogenesis from stage 13 onwards using ctB-gal4 driven expression of nRFP. By stage 13 of embryogenesis, the renal tubules have reached their mature cell number and commence their stereotypical rearrangements (involving convergent extension movements) and navigation to reach highly reproducible 3-D arrangements in the body cavity by stage 16. Z-stacks were taken at regular 4 minute time intervals. Scale bar represents 20ìm. See also Figure 1 and Figure S1.
