Figure 4. EC-specific expression of Arhgef15 in mouse retinas.

Figure 4

(A–D) IHC for lacZ and PECAM-1 in whole-mount retinas (A, B, and D) and retinal cryo-sections (C) of Arhgef15 lacZ/lacZ mice at P5 (A–C) and P17 (D). Note the endothelial specificity of Arhgef15 expression in mouse retinas at early and late postnatal stages. At P17, endothelial expression of Arhgef15 in the superficial vascular layer was diminished in arteries but was maintained in veins. A, artery; V, vein. Scale bar: 200 µm (A); 20 µm (B and C); 50 µm (D).
