NSCs Migration Promoted and Drug Delivered Exosomes‐Collagen Scaffold via a Bio‐Specific Peptide for One‐Step Spinal Cord Injury Repair

Spinal cord injury (SCI) is plaguing medical professionals globally due to the complexity of injury progression. Based on tissue engineering technology, there recently emerges a promising way by integrating drugs with suitable scaffold biomaterials to mediate endogenous neural stem cells (NSCs) to achieve one‐step SCI repair. Herein, exosomes extracted from human umbilical cord‐derived mesenchymal stem cells (MExos) are found to promote the...
