Changes in Otx2 and Parvalbumin Immunoreactivity in the Superior Colliculus in the Platelet-Derived Growth Factor Receptor-β Knockout Mice

Figure 2

Low power photomicrographs of the laminar distribution of Otx2-IR (a) and parvalbumin (PV-) IR (b) elements in the control mouse SC. Two matching series of left coronal sections in 3 AP levels (A–C) are presented. Note prominent Otx2-IR cells in the superficial layers (SLs) and scattered Otx2-IR cells in the intermediate gray layer (IGR) and deep layers (DLs). Also note strong PV-labeling in the SL, patchy PVlabeling in the IGR, and scattered and/or clustered PV-IR cells in the IGR and DL. Number below each section indicate distance from the bregma. PAG periaqueductal gray matter. Scale bar = 200 μm.
(a) Otx2
(b) PV
