HUVECs were cultured at 37 °C in a humidified 5% CO2 environment with HUVEC culture medium (EBM-2 Basal Medium (CC-3156) and EGMTM-2 SingleQuotsTM Supplements (CC-4176), Lonza). Media were refreshed every 2–3 days. Cells were passed using trypsin (Sigma) at 70–80% confluency. HUVECs were used for the scratch-wound healing assay at passage three. HUVECs were stored up to passage three in 90% heat inactivated New Born Calf Serum (NBSCi) (Sigma) and 10% DMSO (Sigma).
