mRNA expression levels by quantitative PCR for selected genes of interest. Quantitative PCR results for three up- and downregulated genes of vascular endothelial growth factor (VEGF)-stimulated or serum-deprived adipose tissue-derived stromal cells compared to control correspond with significant microarray data. ***P < 0.001, **P < 0.01, **P < 0.05. N = 3. BMP6, Bone-morphogenic protein; IGF1, insulin-like growth factor 1; ITGB3, integrin-beta 3; MMP, Matrix metalloproteinase; SE, standard error of the mean; SMOC2, SPARC-related modular calcium binding 2.
