在脊椎动物中枢神经系统发育过程中,大多数少突胶质细胞祖细胞(OPC)在腹侧脊髓中被指定,并且必须在整个神经管中迁移,直到它们均匀分布,占据非重叠区域。虽然这一过程的发展OPC迁移的特点是,管理它的分子介质的性质仍然在很大程度上是未知的。在这里,我们以斑马鱼为模型,证明了Met信号传导是OPCs初始发育迁移所需的,并且使用Met信号传导的细胞特异性敲低,表明Met在OPCs中以细胞自主方式发挥作用。总之,这些研究结果表明,在体内,Met信号在OPC迁移中的作用,并提供了新的见解OPC迁移是如何在发展过程中进行调节。
During vertebrate central nervous system development, most oligodendrocyte progenitor cells (OPCs) are specified in the ventral spinal cord and must migrate throughout the neural tube until they become evenly distributed, occupying non-overlapping domains. While this process of developmental OPC migration is well characterized, the nature of the molecular mediators that govern it remain largely unknown. Here, using zebrafish as a model, we demonstrate that Met signaling is required for initial developmental migration of OPCs, and, using cell-specific knock-down of Met signaling, show that Met acts cell-autonomously in OPCs. Taken together, these findings demonstrate in vivo, the role of Met signaling in OPC migration and provide new insight into how OPC migration is regulated during development.
