    Abstract: Scaffold comprises a polymer defining macropores and comprising hydroxypropylcellulose partially substituted by a substituent comprising a self-crosslinkable group, which is crosslinked through the self-crosslinkable group. The macropores have an average pore size larger than 50 microns and are at least partially interconnected. In one method, bicontinuous emulsion comprising a continuous aqueous phase and a continuous polymer phase is formed. The polymer phase comprises hydroxypropylcellulose partially substituted by a substituent comprising a self-crosslinkable group, and is crosslinked through the self-crosslinkable group to form a polymer defining at least partially interconnected pores. In another method, phase separation is induced in a solution comprising a polymer precursor and water to form a bicontinuous emulsion comprising a continuous polymer phase and a continuous aqueous phase. The polymer precursor comprises a self-crosslinkable group and is crosslinked through the self-crosslinkable group in the emulsion to form a polymer defining at least partially interconnected macropores.

    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.
