NSPC IL-10 suppress clinical scores in EAE. EAE was induced in C57BL/6 mice by subcutaneous injection of 50 μg MOG35-55 peptide in CFA plus intravenous injection of 150 ng Bordetella pertussis toxin. (a) On day 7 after EAE induction or (a) after established EAE disease, mice were intravenously injected with 1 x 106 NSPCIL-10, NSPCs or PBS as indicated. (b) 1 x 106 PKH26-labeled NSPCIL-10, NSPCs or PBS were injected 7 days after induction of EAE in 2D2 mice with MOG35-55. On day 7 after injection, organs were examined by fluorescence microscopy for the presence of PKH26+ cells. Cell nuclei were stained with DAPI (blue). Infiltration was analyzed by H&E stain. NSPCIL-10 and NSPCs were detected within lungs, spinal cords, lymph nodes and brains of MOG35-55 immunized 2D2 mice and in the CNS within cellular infiltrates. Tissues are shown from NSPCIL-10-treated mice as representative examples for NSPC- and NSPCIL-10-treated mice. CFA, complete Freund’s adjuvant; CNS, central nervous system; DAPI, 4’,6-diamidino-2-phenylindole; EAE, experimental autoimmune encephalomyelitis; H&E, hematoxylin and eosin; IL, interleukin; MOG35-55, myelin oligodendrocyte glycoprotein aa 35–55; NSPC, neural stem/progenitor cell; PBS, phosphate-buffered saline.
