Abstract

The present application relates to a lyophilized scaffold composition having at least one polysaccharide wherein said scaffold is substantially solid and capable of being formed into a desired shape; wherein the at least one polysaccharide has a protonation level resulting in controlled rehydration of said scaffold, such that when said scaffold is contacted with at least one of a neutral aqueous solution, blood, blood derived fluid and combinations thereof, said scaffold forms a microparticle dispersion and stimulates tissue remodeling and anabolic wound repair, a process for preparing a lyophilized scaffold composition and the use of a lyophilized scaffold composition for wound repair in a mammal.
