Abstract

original image

Alginate-only, cell-laden, and protein-immobilized hollow fibers are produced (see image). Cells remain alive within the hollow fibers due to the nontoxic fabrication process. Vascular tissue can be emulated by embedding endothelial cells into the alginate hollow fibers and then embedding these cell-laden fibers into smooth-muscle-cell-laden AGF hydrogels.
