The Comparison of Adipose Stem Cell and Placental Stem Cell in Secretion Characteristics and in Facial Antiaging

Figure 4

The analysis of protein-protein interaction of secreted proteins of ASC and PSC. The thickness of line represents the strength of evidence. All proteins could interact with others whether in ASC-CM (a) or PSC-CM (b). The relative active proteins in two kinds of CM were IL6, IL8, MMP-2, TGFB1, VEGFA, IGF-1, and CXCL12 (SDF-1). In ASC-CM, the specific active proteins were CTGF, FN, TIMP-1, and SERPINE-1 (PEDF). And in PSC-CM, the specific active proteins were FGF-2, CCL2, FGF-7, MMP-1, and MMP-9.
