Figure 1

Main transitions in the Schwann cell lineage. A scheme illustrating key cell types involved in Schwann cell development, and in nerve repair. Also shown are the alternative cells that can develop from Schwann cell precursors (SCP) in addition to immature Schwann cells (iSch). Black uninterrupted arrows: normal developmental transitions. Red arrows: the Schwann cell injury response. Stippled arrows: post-repair formation of myelin and Remak cells (with permission from Jessen et al., 2015b).
