| Outline of Final Research Achievements |
We demonstrated that bone marrow stromal cells (BMSC) stimulate axon regeneration directly but also indirectly via activation of glial cells such as astrocytes, choroid plexus epithelial cells (CPECs), and Schwann cells. Conditioned medium from BMSC (BMSC-CM) promoted the production of anti-inflammatory chemokines and reduced inflammatory chemokines in astrocytes. In vivo experiment using spinal cord injury model rat revealed that BMSC-CM administration promoted locomotion compared to control groups. Furthermore, extracellular matrix components, such as collagen types I and IV, and laminin were expressed in the region site and interact with regenerating axon. Similarly, CPEC-transplantation also accelerated recovery from spinal cord injury. Taken together, it was suggested that many glial cells play a roll in axon regeneration after spinal cord injury, and BMSC-CM enhance glial cell function. Further investigation is needed to develop a novel therapy with regulating glial cells.
