Real-time reverse transcription-polymerase chain reaction (RT-PCR). a–g Representative graphs showing expression of the angiogenesis-related genes vascular endothelial growth factor A (VEGF-A) (a), angiopoietin 2 (Ang-2) (b), platelet endothelial cell adhesion molecule 1 (PECAM-1) (c), fibroblast growth factor (FGF) (d), angiopoietin 1 (Ang-1) (e), von Willebrand factor (vWF) (f) and platelet-derived growth factor (PDGF) (g) in human umbilical vein cord endothelial cells (HUVECs) grown under different culture conditions at 2, 3 and 7 days. Data normalized to glyceraldehyde-3-phosphate dehydrogenase (GAPDH) as housekeeping gene and presented as mean ± SEM. *p ≤ 0.05, **p ≤ 0.01, ***p ≤ 0.001, n = 4.
