Fig 6. IHC was carried out to visualize GFP expression in the lumbar spinal cord.

Fig 6

Shown are representative 40 micron lumbar spinal cord sections of all study macaques, stained for GFP. Magnified insets show examples of GFP-positive motor neurons. Macaque ID numbers are provided in each panel, along with a qualitative scoring of ventral horn expression. The (-) indicates no GFP-positive staining above that seen in uninjected NHPs; (+) indicates some positive cells observed, above that seen in uninjected macaques; (++) indicates relatively strong expression in a large number of neurons.
