cardiovascular system
• tamoxifen-treated mice exhibit decreased radial length, vascular density, endothelial cell proliferative activity, sprouting activity, and pericyte coverage compared with control mice
• tamoxifen-treated mice exhibit decreased vascular density in the superficial and deep vascular plexus layers compared with control mice
• tamoxifen-treated mice exhibit disorganized, regressed, disconnected and dilated retinal vessels compared with control mice
• 4-fold increased vessel leakage following oxygen-induced retinopathy in tamoxifen-treated mice

vision/eye
• tamoxifen-treated mice exhibit decreased radial length, vascular density, endothelial cell proliferative activity, sprouting activity, and pericyte coverage compared with control mice
• tamoxifen-treated mice exhibit decreased vascular density in the superficial and deep vascular plexus layers compared with control mice
• tamoxifen-treated mice exhibit disorganized, regressed, disconnected and dilated retinal vessels compared with control mice
• following oxygen-induced retinopathy, mice exhibit increased avascular area, neovascular tuft area and reduced pericyte coverage in the superficial layer with disorganized, regressed, disconnected and dilated deep layer vessels, 4-fold increased vessel leakage and 4-fold increase in multifocal hemorrhages compared with control mice

nervous system
• decrease in GFAP+ cell densities in tamoxifen-treated mice
• however, the number of Pax2+ astrocytes is normal

homeostasis/metabolism
• following oxygen-induced retinopathy, mice exhibit increased avascular area, neovascular tuft area and reduced pericyte coverage in the superficial layer with disorganized, regressed, disconnected and dilated deep layer vessels, 4-fold increased vessel leakage and 4-fold increase in multifocal hemorrhages compared with control mice
