CGFs enhance the expression of pro-angiogenic factors in endothelial cells. HUVECs were incubated with CGF-CM (10%) or culture medium (CTR) for 4 hm and mRNA levels of Ang-1, Ang-2, PDGF-B, FGF-2, TGF-β1, and BMP-2 were analyzed by qRT-PCR and expressed as fold over unstimulated control (CTR) (mean ± SD). Each experiment consisted of four replicates for each condition. * p < 0.05 vs. CTR.
