Fig. 1. Respecification of the AP axis of the inner ear at E1.5. (A) The surgery
for AP reversal. DiI crystals were spotted in the anterior region of a right
otic cup before replacing a left donor otic cup. (B) Bright-field and (C)
fluorescent micrographs showing DiI labeling in a transplanted otocyst 24
hours after surgery. Arrows indicate DiI labeling in the transplanted otocyst.
(D,E) Similar Lfng expression patterns (arrows) in controls (D) and
AP rotated otocysts (E). A, anterior; D, dorsal. Scale bar: 100 µm.
