要 旨 / Abstract
In recent years, stem cell transplantation has emerged as a potential therapeutic strategy for spinal cord injury (SCI), and several early-phase clinical trials have been completed. However, its efficacy and long-term safety remain unproven, especially in the chronic transplantation for SCI. One of the failure causes can be ascribed to the glial scar, which strictly segregates the lesion and the spared area after SCI. The process of glial scar formation, astrogliosis, has long been considered to be unidirectional and irreversible, however, we recently demonstrated that the process of glial scar formation is regulated by environmental cues, such as fibrotic extracellular matrix material. In this seminar, I will talk about the new concept for spinal cord regeneration based on glial biology.
