Secretions of the angiogenic factors VEGF, HGF, and IGF-1 following co-culture of ASCs or ST2 cells with Gr1+, F4/80+, or CD11c+ cells. Comparisons are made with monocultures (non). Data are presented as means ± standard deviation. *P < 0.0001, **P < 0.001, ***P < 0.005, versus monocultured cells; Dunnett’s test (n = 5). ASC, adipose tissue-derived stromal cell; HGF, hepatocyte growth factor; IGF, insulin-like growth factor; N.D., not detected; ST2 cell, bone marrow-derived stromal cell; VEGF, vascular endothelial growth factor.
