N | normal phenotype |
• increase in the number of endothelial tip cells at the angiogenic front of P5 retinas
• P8 retinas display areas of sheet-like endothelium that lacks defined arterioles and venules
• retinas show extensive presence of arteriovenous shunts and vascular tangles
|
• increase in vessel density in retinas compared to either single mutant
• reduction in vessel outgrowth at P5 in retinas
• retinal capillaries exhibit gaps in pericyte coverage
• P5 retinas show altered vessel structures with pericytes located at a greater distance from the vessel lumen, indicative of pericyte dissociation
• the intracellular region between pericytes and endothelial cells appears wider, less dense and has visible large open spaces indicating that pericytes fail to associate properly with the endothelium
• retinal vessels of P5 mice show loss of mural cells
• P5 retinal capillaries exhibit numerous granular osmiophilic material in the vicinity of pericytes and not associated with endothelial cells
