aFGF: acidic fibroblast growth factor; AT-MSC: adipose tissue-derived MSC; BM-MSC: bone marrow-derived MSC; GCS-F: granulocyte-colony stimulating factor; HGF: hepatocyte growth facctor; IL: interleukin; IP-10: interferon-gamma induced protein 10; MCP-1: monocyte chemotactic protein 1; MMP: metalloproteinase; nd: not determined; PDGF-AA: platelet derived growth factor AA; pg: picogram; PLGF: placental growth factor; TGF: transforming growth factor; VEGF: vascular endothelial growth factor; WJ-MSC: Wharton’s Jelly-derived MSC.
Protein concentration is expressed in pg secreted per million cells and per day. ANOVA and Bonferroni tests (α = 0.5, n = 3) were applied for each quantified factor in order to determine significant differences between all three MSC. For a specific protein; different letters (superscript letters a, b and c) mean statistically different expression levels.
