Expression pattern of lhx9 in zebrafish embryogenesis and retinogenesis. (A–G′) lhx9 expressed in the zebrafish embryo at 24 hpf, 48 hpf, 60 hpf, 72 hpf, 96 hpf, and 5 dpf. t, telencephalon; E, eye; e, epiphysis; d, diencephalon; m, mesencephalon; mhb, mid-hindbrain boundary; hb, hindbrain; ht, heart; pf, pectoral fin; asterisk, hypothalamus; Scale bar, 500 μm. (H1–H8) The expression of lhx9 in the zebrafish retina at 24 hpf, 36 hpf, 48 hpf, 60 hpf, 72 hpf, 96 hpf, 5 dpf, and 6 dpf. Figures are horizontal sections along the temporal-nasal axis (T–N). ONL, outer nuclear layer; INL, inner nuclear layer; GCL, ganglion cell layer; OPL, outer plexiform layer; IPL, inner plexiform layer. Scale bar=20 μm.
