Summary:Heparin, the well‐known anticoagulant polysaccharide, is also active in many other biological systems owing to its structural similarity to HS, but usually lacks selectivity because it is more highly sulfated. A series of straightforward chemical reactions (de‐O‐sulfation, de‐N‐sulfation and re‐N‐acetylation), carried out to partial or complete extent, were combined, resulting in a number of modified heparin polysaccharide derivatives with altered properties. These exhibited a range of abilities to promote cell signalling through the FGF/FGFR tyrosine kinase signalling system, in an in vitro cell assay with combinations of FGF‐1, ‐2, ‐3 and FGFR 1 and 3. One polysaccharide (N‐acetylated, 6‐O‐ and 2‐O‐sulfated heparin), with only a fraction (<10−3) of the anticoagulant activity of heparin (200 U · mg−1), promoted FGF‐2‐mediated angiogenesis (10‐fold) and therefore had an improved ratio of pro‐angiogenic activity to anticoagulant activity in excess of 104compared to heparin. These results demonstrate that heparin‐derived polysaccharides can be engineered for selected activities and have potential in a wide range of medical, biotechnological and tissue‐engineering applications.Effect of selected engineered heparin polysaccharides on angiogenesis.
