Deregulated retinal angiogenesis directly cause vision loss in many ocular diseases, such as diabetic retinopathy and retinopathy of prematurity. To identify endothelial-specific genes expressed in angiogenic retinal vessels, we purified genetically labeled endothelial cells from Tie2-GFP transgenic mice and performed gene expression profiling using DNA microarray. To find out genes associated with angiogenesis, comparisons of microarray data were carried out between GFP-negative non-endothelial retinal cells and GFP-positive retinal endothelial cells in angiogenic P8 retina. Eighteen arrays are included. Utilizing fluorescence-activated cell sorting (FACS), we isolated endothelial cells as GFP-positive cells from P8 retina in homozygous Tie2-GFP transgenic mice. GFP-negative cells were served as non-endothelial control. RNA extracts from sorted cells were amplified and then hybridized to Affymetrix MGU74v2 series arrays in triplicate.
