MSCs-IFNβ-treated mice showed inhibition of experimental autoimmune encephalomyelitis (EAE) onset, and the maximum and average score for all animals in each group was significantly lower in the MSCs-IFNβ-treated EAE mice when compared with the MSCs-GFP-treated EAE mice. The gene discussed is IFNB1; the disease is experimental autoimmune encephalomyelitis.
