Fig. 2. Micrographs showing Lim1 immunohistochemistry in BrdU-, cytochalasin D- and Colcemid-treated retinas. Fluorescence micrographs showing (A-E) Lim1 (green) and BrdU (red) labelling in retinas at different developmental stages. See also Table 1. Arrows in A and B indicate double labelled cells. (F-H) Micrographs showing Lim1 (green) and Ng-CAM (red) in (F) cytochalasin D-treated, (G) Colcemid-treated and (H) control-treated retinas. Embryos were analysed at stage 33. gcl, ganglion cell layer (always oriented down); inl, inner nuclear layer; st, stage. Scale bars: 20 µm.
