- 요약Hydrogels have emerged as a powerful vehicle for drug delivery and cell delivery to promote tissue regeneration. Recently, there has been a focus in mimicking the viscoelasticity of tissues in the hydrogels to optimize their performance. Among these, dynamic covalent crosslinked (DCC) hydrogels are notable for their viscoelastic and injectable nature, making them ideal for both therapeutic and cell delivery applications.First, we discuss the impacts of an often-overlooked parameter-crosslinker architecture-on the mechanics of DCC hydrogels. Results unveil the distinct ranges of tunable stiffness and viscoelasticity based on crosslinker architectures. This provides insight into optimal matrix mechanical properties for 3D culture of chondrocytes for engineered cartilage, where fast stress relaxation and intermediate matrix degradation are potentially preferred.Next, we present the application of DCC hydrogels in bacteriophage (phages) delivery to combat life-threatening infections caused by nosocomial pathogens, particularly Pseudomonas aeruginosa (Pa). Hydrogel systems capable of sustained delivery of high-titer phages were developed, demonstrating superior bacterial burden reduction in a novel in vivo chronic wound infection model, compared to systemic phage treatment.Finally, we examine how the cancer cells generate forces to divide in viscoelastic hydrogels. Single cancer cells were found to generate substantial pushing forces to drive cell division in confining collagen gels, and neither cell spreading nor matrix degradation are found to be required for mitotic elongation. These results provide insights into how tumor cells proliferate in dense, collagen-rich tissues.Overall, this work highlights the translational potential of viscoelastic hydrogels in both regenerative medicine and therapeutics delivery, demonstrating the versatility of this class of biomaterials.
