Abstract

The biomedical applications of chitosan have been widely researched. FN mediates its biological effects through binding to the hetero-dimeric transmembrane glycoproteins, integrins, which physically couple the cytoskeleton to the ECM. FN binds to the integrin through a consensus site including the Arg-Gly-Asp (RGD) sequence within tenth type III module (Ruoslahti & Pierschbacher 1987). A short sequence Pro-His-Ser-Arg-Asn (PHSRN) has also been identified as a synergistic motif within ninth type III module for binding to ${\alpha}$5${\beta}$1 integrin (Aota et al. 1994). (omitted)
