Movie S8. NPCs express myelin proteolipid protein (PLP) and wrap around damaged axons. PLP-GFP-NPCs (green) and Thy1-YFP+ axons (yellow) are visualized under 2P excitation 2 wk following transplant into a JHMV-infected Thy1-YFP spinal cord. PLP-GFP wrapping is highlighted in red. Movie duration = 36:11 (min:s). (Scale bar, 10–5 μm.)
