    Article Title: GlycoRNA complexed with heparan sulfate regulates VEGF-A signalling
    Article Snippet: MOLM-13, U2OS, HUVECs and keratinocytes were all treated for 45 min. For heparinase treatment, heparinase I (NEB), heparinase II (NEB) and heparinase III (NEB) were added directly to the cell culture at a final concentration of 4 units per millilitre (each) for 30 min. For sodium chloride (NaCl) and sodium chlorate (NaClO 3 ) treatment, NaCl and NaClO 3 were added to the cell culture at a final concentration of 50 mM for 24 h. For exogenous Tega HS chain treatment, rHS09 (TEGA Therapeutics) and rHS37 (TEGA Therapeutics) were added directly to the cell culture at a final concentration of 4 μM for 60 min. For serum starvation, HUVECs were cultured in vascular cell basal medium (PCS100030, Bioresource Center) without endothelial cell growth kit-VEGF (Bioresource Center) after being washed briefly three times with phosphate buffer saline (PBS).
