Expression of COUP-TFI and COUP-TFII during mouse retinal development. A, B, Frozen-sectioned eyes from wild-type mice at the indicated developmental stage were immunostained with anti-COUP-TFI and -COUP-TFII antibodies (green). The nuclei were stained with DAPI (blue). The arrows and arrowheads in the panels are described in Results. Scale bars, 100 μm. D, Dorsal; V, ventral. C, D, Schematic representation of the expression patterns of COUP-TFI (red, C) and COUP-TFII (yellow and brown, D). L, Lens; NBL, neuroblastic layer.
