FIG. 2.
Hair cell-specific expression of Gfi1-Cre in the vestibule. (a–l) In situ hybridization experiments reveals the expression pattern of Gfi1 at E13.5 (a–c), E14.5 (d,e), E15.5 (f,g), E16.5 (h,i), E17.5 (j,k) and P0 (l). (a′–l′) X-Gal staining of vestibular sections at E13.5 (a′–c′), E14.5 (d′, e′), E15.5 (f′,f″–g′), E16.5 (h′–i′), E17.5 (j′–k′) and P0 (l′) shows the Cre-recombinase-mediated activation of lacZ expression in the Gfi1Cre/+; R26R-lacZ ears. Abbreviations: lc, lateral semicircular canal; mu, macula of utricle; s, saccule. Scale bars represent 50 μm.
