Localization of Olf-1 in the mouse retina. Olf-1 protein was detected by immunoperoxidase reactivity in the mouse retina at all ages examined, including E12 (A), E14 (B), E16 (C), PD1 (D, E), and adult (F). Lens (L) is at thebottom in A–D. Inner layer (IL), outer layer (OL), neural retina (NR), optic nerve (ON), iris (I), cornea (C), and pigmented retina (PR) are indicated. The darkened PR in D was also observed with preimmune serum. Olf-1 protein resided in cells of the ganglion cell layer (GCL) (D), and a high-magnification view (E, F) revealed a few Olf-1-positive cells in the inner nuclear layer (INuL).
