EI, endothelial index; NEI, nonendothelial index; WT, wild type; Exp, experiment.
Total number of nuclei counted.
Percentage of replicating cells as determined by labeling with the mitotic marker phosphohistone H3.
Number of nuclei with PECAM-labeling along the cell border.
Nuclei of cells that did not exhibit PECAM-labeling.
Formula used to express each endothelial index as a percentage of its companion nonendothelial index.
