Dextran was carboxymethylated and sulfated to prepare sulfated CM-dextrans with various degree of substitution in order to investigate the interaction between acidic polysaccharides and fibroblast growth factors (FGFs). It was shown that CM-dextran with low degree of sulfation slightly activated FGFs. It was concluded that the degree of anionization was more effective than the kinds of sugars or linkages on the activation of FGFs.
