Expression pattern of LKB1 in cochlea hair cells of mice at p30.

<p>(A) Confocal images of cochlea hair cells in wild-type mice. LKB1 was expressed from the cuticular plate to the nuclei of hair cells. Left panel: LKB1 expression was detected in the cuticular plate. Right panel: LKB1 expression was detected in the hair cell nuclei. (B) Confocal images of cochlea hair cells in the Atoh1-LKB1^-/- mice. LKB1 was deleted in the cochlea hair cells of the inner ear. Left panel: LKB1expression was not detected in the cuticular plate. Right panel: LKB1 expression was not detected in the hair cell nuclei. Green, phalloidin, an F-actin specific dye. Red, LKB1. Bule, Dapi. Scale bar: 20 μm.
