Formation of DA and NPY amacrine clusters is inhibited when mitosis is repressed during optic vesicle stages.A, The percentage of DA amacrine cells found in clusters is completely inhibited when embryos are incubated in DNA replication inhibitors starting at stage 21. The percentage of clusters remains significantly repressed during optic vesicle stages (23–25) and gradually returns to nearly 50% of the normal level by optic cup stages (31). B, The percentage of NPY amacrine cells found in clusters is significantly repressed during optic vesicle stages (23–25) and returns to nearly 50% of the normal level by optic cup stages (31). C, The percentage of LB-5-HT amacrine cells found in clusters is reduced to slightly >50% during optic vesicle stages and returns to near normal by optic cup stages.St., Stage.
