Fig. 2 (Left). Cell proliferation in nascent sensory compartments of the stage 47 X. laevis inner ear, three hours after transient exposure to BrdU. Anterior to posterior sections representing the entire inner ear (A-D) show the presence of BrdU-positive cells (deep black; arrows) in the epithelia of all endorgan compartments. (A) BrdU- positive cells are more prevalent in the ventral regions of the utricle in anterior sections. (B) BrdU-positive cells are distributed throughout the epithelium of the utricle, horizontal canal, sacculus and anterior canal. (C) BrdU incorporation was detected in the saccular sensory epithelium and in the sensory ganglion. (D) BrdU-positive cells are visible in the lagena and posterior canal in posterior sections of the inner ear. (E) BrdU-positive cells were detected in the ventricular zone of the brain. (F) Control section processed for immunohistochemistry with secondary antibody but without primary (anti-BrdU) antibody. Hematoxylin counterstain (grey). Scale bar, 100 μm.
