This suggests that the transplanted, control cells move from the eye field to
the surface ectoderm outside the neural plate.
YFP expressing cells are also observed in
the surface ectoderm and left half of the forebrain (G).
It is interesting that YFP - expressing pluripotent cells were rarely detected in the lens, yet often present in the cornea since
the surface ectoderm forms both the lens and the cornea.
