Expression of α7 integrin and β-gal in the olfactory nerve.

<p>A-C: Anti-α7 integrin (ITGA7, red) and Hoechst nuclear stain (blue) show the presence of α7 protein in <i>α7</i>^<i>+/+</i> (A) but not <i>α7</i>^{<i>lacZ/lacZ</i>} (B) olfactory nerve (ON, arrowheads), olfactory nerve layer (ONL) and glomerular layer (GL). Adjacent <i>α7</i>^{<i>lacZ/lacZ</i>} section (C) has <i>α</i>7/β-gal reactivity (green) in the ON and ONL (arrowheads). D-F: OECs in the ON are marked with arrowheads and show antibody expression in <i>α7</i>^<i>+/+</i> (D) or <i>α</i>7/β-gal in <i>α7</i>^{<i>lacZ/lacZ</i>} nerve (F). The <i>α7</i>^{<i>lacZ/lacZ</i>} negative control shows only Hoechst-labeled nuclei (E). Scale bar A-C: 100 μm; D-F: 20 μm.
