Expression of COUP-TFs in BMPR CKO mouse retina. A–D, Frozen sections of control and BMPR CKO mouse eyes at E14.5 were immunostained with anti-COUP-TFI (A, B) and anti-COUP-TFII (C, D) antibodies. The panels in the left column show nuclear staining by DAPI. B and D are enlarged views of the dorsal and ventral regions in the right panels of A and C. The regions are indicated by dashed boxes.
