Hematoxylin–eosin staining of a rat spinal cord with acute balloon-induced spinal cord compression lesion. Spinal cord injury (SCI) only: longitudinal section of the spinal cord with a cavity in the control animal at 6 months after SCI. SCI + hydrogel + mesenchymal stem cells (MSCs): spinal cord at 6 months after a lesion with MSC-seeded HPMA-arginine–glycine–aspartic acid hydrogel implanted at 5 weeks after SCI. Motor test and sensory test: A comparison of motor test (Basso, Beattie, and Bresnahan score) and sensory test (plantar test) in 1–25 weeks after SCI in rats with SCI only, SCI and hydrogel implantation, and SCI with implantation of hydrogel seeded with bone marrow mesenchymal stem cells.
