Web14 Mar 2024 · Glial cells regulate multiple aspects of synaptogenesis. In the absence of Schwann cells, a peripheral glial cell, motor neurons initially innervate muscle but then degenerate. Here, using a genetic approach, we show that neural activity-regulated negative factors produced by muscle drive neurodegeneration in Schwann cell-deficient mice. Web1 Aug 2013 · The main mechanism responsible for locomotor recovery of these animals is the ability of hESC-derived OPCs and MPs to differentiate into neuronal and glial cells after transplantation. However, it seems that the regenerative mechanism of hESC therapy for SCI does not depend exclusively on the differentiation potential of transplanted cells.
