Packed Hydrogel Microfibers as Scaffolds Supporting Dynamic Cellular Behavior and Biomaterial Inks in 3D Printing

Advanced Healthcare Materials, EarlyView.
Packed hydrogel microfiber (PHM) materials consist of flexible and high aspect ratio hydrogel components that, as a bulk material, are simultaneously mechanically robust and dynamic. Cells cultured in or on PHM scaffolds can be influenced by topographical cues or interact with a dynamic environment that permits cell spreading and multicellular ...
