Timelapse of wild type donor cells in a wild type host. Donor cells (magenta) originating in the midline region move through the prospective optic stalk and into the optic cup. Cells maintain a bipolar morphology, and one cell contributes to the nasal optic fissure margin. Maximum intensity projection of donor cells (magenta, fluorescent dextran lineage tracer) superimposed on average projection of host membrane label (green, Tg(bactin2:EGFPCAAX)). Time interval between stacks, 6.25 minutes. Dorsal view.
