Claims10
A microfiber having a core/shell structure, the microfiber comprising:
- a micro gel fiber forming a core of the core/shell structure;
- and
- a high strength hydrogel forming a shell of the core/shell structure that covers the micro gel fiber,
- wherein the micro gel fiber completely occupies an interior volume defined by the shell.
A cell fiber obtainable by removing a cover of high strength hydrogel from a microfiber containing cell culture in a micro gel fiber, wherein the micro gel fiber comprises a hydrogel selected from the group consisting of chitosan gel, collagen gel, gelatin, peptide gel, and mixtures of the foregoing, or comprises fibrin gel together with a hydrogel selected from the group consisting of chitosan gel, collagen gel, gelatin, peptide gel, and mixtures of the foregoing.
