Altered retinal vascular formation in forskolin-treated Mrp4-knockout mice. (A) Whole-mount immunostaining for PECAM in P6 retinas from WT, Mrp4^+/−, and Mrp4^−/− mice after intraperitoneal forskolin or DMSO administration from P4 to P5. (B) Quantification of the vascular parameters. P value is <0.01 (*). There is a significant difference between forskolin-treated Mrp4^+/− mice and forskolin-treated WT mice or DMSO-treated Mrp4^−/− mice (P < 0.01) (†). A, artery; V, vein. The data are provided as the mean ± SD.
