These findings are the first to identify upregulated C6st1 gene expression correlating with the motility of Schwann cells that guide growing axons through both developmental and injured environments.</jats:p> Upregulation of chondroitin 6-sulphotransferase-1 facilitates Schwann cell migration during axonal growth Journal of Cell Science |
