Multistructured hydrogel promotes nerve regeneration

Hydrogels have emerged as promising biomaterials for nerve regeneration due to their adjustable properties, structural resemblance to the extracellular matrix, and ability to promote cell adhesion and proliferation. This comprehensive review discusses the advantages, challenges, and future directions of various functional hydrogels. Advanced technologies for fabricating Multistructured hydrogel, including injectable hydrogels, hydrogel microspheres, fibrous hydrogels, 3D printing hydrogels, nanogels, stem cell-loaded hydrogels, electrical hydrogels, ultrasound hydrogels, and magnetic hydrogels, have been developed and studied for nerve regeneration. These technologies demonstrate the versatility of hydrogels in neural tissue repair. However, challenges such as biocompatibility, degradation rates, and scaffold design need to be addressed. Interdisciplinary research is necessary to develop innovative hydrogel systems that overcome these challenges and realize the potential of hydrogels for nerve regeneration. This review provides valuable insights into advanced hydrogel technologies and highlights their potential in regenerative medicine, particularly in neural regeneration. Researchers can use this knowledge to refine therapeutic approaches involving hydrogels for enhancing nerve regeneration.
