six7 acts cell autonomously.
(A) six7fl4-donor cells or (B) WT-donor cells were labeled by the tracer rhodamine-dextran, transplanted into WT genetic background and allowed to develop until 4 dpf. Expression of rods (4C12, green) and green-sensitive opsin (pink) were detected by whole mount immunolabeling. Note that six7fl4-transplanted cells frequently differentiate as rod photoreceptors (orange, arrows) and rarely immunolabeled for green-sensitive opsins while neighboring WT cells differentiate as green-sensitive cones. Significant difference was observed in the percent of six7fl4-donor cells that differentiate into rods or cones compared to WT donor cells (χ2, p<0.0001).
