报告简介:The dynamic properties of polymeric biomaterials at molecular level impart significant impact on the cellular behaviors. Developing tunable molecularly-dynamic polymeric biomaterials is highly instrumental to the fundamental investigation on cellular responses to the dynamic cues in extracellular environment. For example, cellular adhesion is controlled by the dynamic ligation process of surface receptors, such as integrin, to adhesive motifs, such as Arg-Gly-Asp (RGD). Remote control of adhesive ligand presentation on biomaterial surfaces can offer benefits in regulating cell-implant interactions, thereby immune responses or tissue regeneration in vivo. Herein we present a strategy for modulating nanoscale ligand oscillations on 2D biomaterial substrates by adjusting the frequency of an oscillating magnetic field to modulate the adhesion and specialization of stem cells and macrophages. To investigate 3D culture of cells in hydrogels with dynamic network structures, we have developed a series of dynamic hydrogels based on reversible crosslinks with unique properties such as resilient mechanical property, fast relaxation, self-healing, bioadhesiveness, injectability, and promoting recruitment of endogenous cells. These hydrogel properties are not only desirable for potential clinical applications of these hydrogels but also useful for studying the effect of microenvironmental mechanical cues on stem cell behaviors.
