(C) Differentially expressed genes using RNAseq transcriptome analysis of CD31+ endothelial cells (ECs) sorted from sprouting EBs from Apelin STOP cells stimulated with VEGF (30ng/mL) and DMSO (-Apln) and repaired Apelin GO sister cells stimulated with VEGF and Apelin (1000nM) (+Apln). VEGF target genes and angiogenesis-related genes, predicted by Ingenuity Pathway Analysis (IPA) software, are indicated by bars on the upper axis of the heatmap. GO terms were analyzed by DAVID on-line software.
