tRG cells express Pax6 during and after neurogenesis.

<p>(<b>a–c</b>) 4A4+ tRG cells (green) in the E17 rat somatosensory cortex that express Pax6 (red). Blue channel shows DAPI staining. (<b>d–f</b>) Examples of 4A4+ tRG cells (green) in post-neurogenic somatosensory cortex of macaque (<b>d</b>), ferret (<b>e</b>), and rat (<b>f</b>) that also express Pax6 (red). Blue channel shows DAPI staining. Scale bar in left panels applies to all panels in each set.
