Movie 3

HC cell cycle in a developing retina. Light-sheet time-lapse imaging of PCNA dynamics from HC birth to its final cell cycle. Mosaic expression of hsp70:GFP-PCNA (magenta, nuclei) and Trβ2:tdTomato (green, HCs and PRs). White arrowhead points to the tracked HC. Cyan and red arrowheads point to HC sister cells after HC final division. Time interval 5min. Time in h:min and scale bars = 10 μm. Related to Figure 2.
