Fig 5. Tet2 and tet3 regulate retinal neurogenesis cell non-autonomously.

(A) Chimeric embryos were generated by blastomere transplantation from fluorescent dextran-labeled donor into unlabeled host. Retinae composed of clones from wild-type and tet2^-/-;tet3^-/- mutant cells were analyzed at 3dpf. (B) Sibling donor to wildtype host transplants yielded clones of donor cells (green; arrows) that differentiated normally into retinal neurons including AC, RGC, rods (red), and display proper lamination (n = 5). (C) Similarly, tet2^-/-;tet3^-/- mutant cells transplanted into genetically wildtype hosts also differentiated normally, and the regions of the retina containing mutant clones were also properly laminated (n = 3). (D). Genetically wild-type donor cells transplanted into tet2^-/-;tet3^-/- mutant host retinae failed to undergo neurogenesis and remained undifferentiated (green, arrows) (n = 3). DNA (blue), HuC/D + zpr-3 antibody stain (red), transplanted donor clones (green). All images are 3dpf. Dorsal is up and anterior to the left. Scale bar = 50μm
