A decellularized spinal cord extracellular matrix-gel/GelMA hydrogel three-dimensional composite scaffold promotes recovery from spinal cord injury via synergism with human menstrual blood-derived stem cells

The DSCG, GelMA, and MenSCs were cross-linked by photoinitiators under UV irradiation to make composite scaffolds. The MenSC-encapsulated composite scaffolds were then transplanted into a rat model with complete spinal cord transection.
