Abstract: Disclosed is a method for filling a root canal in a tooth. The method includes positioning a fiber in the root canal of the tooth, filling at least a portion of the root canal with an unset hydrogel composition, such that the unset hydrogel composition contacts at least a portion of the fiber, setting the hydrogel composition, thereby forming a set hydrogel, and removing the fiber from the set hydrogel, thereby leaving a channel in the set hydrogel. Methods and kits for repairing teeth are also described.

Abstract: Biomaterials for tissue regeneration and engineering applications and methods of making and use thereof are described, as well as constructs and kits derived from the biomaterials. The biomaterials can be derived from extracellular matrix and functionalized to make them crosslinkable and amenable to tuning of their material properties.

Abstract: The present invention provides engineered models that recapitulate bone marrow, including the endosteal and vascular niches, and bone marrow diseases. The models can be implemented in many ways including, but not limited to, on a microfluidic device or microfluidic chip, a culture model in vitro, and as an implantable model in vivo. Also provided are methods of using these models, including high-throughput systems and in personalized medicine analysis. Also provided are devices for use in the provided bone marrow models, and kits that include at least one such device.
