Description
ASCs cultured in complete medium, ASCs cultured in serum serum-deprived medium, and ASCs stimulated with VEGF in serum-deprived medium were compared. Using microarray analysis, gene expression from the whole genome was compared between conditions. Compared to ASCs in complete medium, expression of 190 and 108 ASC genes were significantly regulated altered by serum deprivation and serum deprivation combined with VEGF, respectively. No significant differences in gene expression patterns between serum-deprived ASCs and serum-deprived ASC combined with VEGF stimulation were found. Genes most prominently and significantly up-regulated by both conditions were growth factors (IGF1, BMP6, PDGFD, FGF9), adhesion molecule CLSTN2, extracellular matrix related proteins like matricellular proteins SMOC2, SPON1 and ADAMTS12, and inhibitors of proliferation (JAG1). The most significantly down-regulated genes included matrix metalloproteinases (MMP3, MMP1), and proliferation markers (CDKN3) and GREM2, - a BMP6 antagonist.
