Neuroinduction and neuroprotection co-enhanced spinal cord injury repair based on IL-4@ZIF-8-loaded hyaluronan–collagen hydrogels with nano-aligned and viscoelastic cues

We developed a nano-aligned and viscoelastic hydrogel matrix embedded with IL-4@ZIF-8. This biomimetic hydrogel combining neuroinductive cues and neuroprotective cues showed promising prospects in SCI repair.
