growth/size/body
• with postnatal tamoxifen treatment from P1-P3, pups are generally smaller than tamoxifen-treated control littermates

vision/eye
• perpendicular sprouting and neovascularization of the deeper retina are strongly compromised with tamoxifen treatment between P5 and P9

cardiovascular system
N
• stability of blood vessels is not affected in mutants with tamoxifen treatment at P1; stability of established vessels in the superficial capillary plexus is not affected with tamoxifen administration between P5 and P9
• postnatal tamoxifen treatment from P1-P3 results in decreased coverage of retinal arteries by vascular smooth muscle cells; however pericyte coverage of capillary beds shows no change
• perpendicular sprouting and neovascularization of the deeper retina are strongly compromised with tamoxifen treatment between P5 and P9
• postnatal tamoxifen treatment from P1-P3 to delete Jag1 in endothelial cells results in significant decreases in numbers of filopodia and filopodia-extending endothelial tip cells
• postnatal tamoxifen treatment from P1-P3 results in strong inhibition of angiogenesis in the retina resulting in reduced branching and delayed extension toward the periphery

• all mice treated with tamoxifen at birth form cerebral cavernous malformations in the brain by 2 months which progress in severity over time
• the lesions in mice treated with tamoxifen at birth show dilated, thin-walled caverns surrounded by hemosiderin deposits, inflammation, and fibrosis
• mice treated with tamoxifen at birth first show vessel dilation and failure of plexus coalescence in the vascular network at P7, and over time the vascular dilations resolve into caverns and appear as mature retinal cerebral cavernous malformation by P21
• cerebral cavernous malformation lesions in tamoxifen treated mice arise from the superficial vascular plexus and remain superficial until later in disease progression
• mice treated with tamoxifen at P7 develop lesions in the periphery of the retina by P21; these lesions show a similar morphology as those from mice treated with tamoxifen at birth, however severity and size are smaller
• mice treated with tamoxifen at P21 do not develop retinal lesions
• mice treated with tamoxifen at birth exhibit vascular leak in the brain
• mice treated with tamoxifen at P1 exhibit retinal endothelial hypersprouting
• mice treated with tamoxifen at birth develop simple, dilated telangiectasias that progress to large multi-chambered caverns over time
