Abstract: Foam-formed collagen strands and methods for forming strands involve depositing a dispersed solution of an isolated cleaned, de-fatted, enzymatically-treated (or non-enzyme treated) human-derived collagen product having a preserved amount of its natural constituents into grooves of a grooved plate, and processing the dispersed collagen product to provide a foam-formed collagen strand. Foam-formed collagen strands may be processed into threads having a matrix of reticulated pores to conduct biological materials in and through the strand, the collagen of the collagen strand comprising isolated, enzymatically-treated human derived collagen having a preserved amount of its natural collagen constituents.

Abstract: A process for producing a polysaccharide sponge comprises the steps of (A) freezing a photoreactive polysaccharide solution, and (B) irradiating the frozen photoreactive polysaccharide solution with light to crosslink the photoreactive polysaccharide, thereby obtaining the polysaccharide sponge. The process includes simplified steps requiring no removal of solvent, and has such an advantage that impurities are easily removed therefrom.
