Figure 3. Expression patterns of Elovl4 mRNA in developing mouse retinas

Mouse eye tissue sections hybridized with Digoxigenin-labeled Elovl4 RNA probes are shown. Panels A-C and D-L show sections derived from embryonic day 15 (E15) and different postnatal days (with the first 24 h after birth defined as postnatal day 0, P0), respectively. Panels B and K were hybridized to the sense probe; the other sections were hybridized to antisense probes. Arrowheads point to the inner segment. Abbreviations: gcl, ganglion cell layer; inl, inner nuclear layer; is, photoreceptor inner segment; le, lens; on, optic nerve; onl, outer nuclear layer; ret, retina; vz, ventricular zone; P1, P3, P7, P14, P22, postnatal day 1, 3, 7, 14, and 22, respectively. Scale bars represent 100 μm in A, B, G, and H and 50 μm in the other panels.
