Summary

[edit]
Description
English: Onset of Ptf1a expression in individual cells. Time-lapse (10 minutes/frame) of wild-type hosts with transplanted cells from Tg(ptf1a:GFP)/H2B:RFP RNA injected embryo to reveal individual cells (38 to 58 hpf). Transplanted (red) cells turn on Ptf1a:GFP expression in the apical half (top) of the developing neuroepithelium, but not always at the apical surface, as cells have started migrating basally. The cells in this movie can be followed through the movie and are shown to move to the developing amacrine layer in the centre of the retina, without ever dividing again (Figure 4). Framerate: 0.1 seconds/frame.
