(Lower panel) In CIA mice treated daily with 2.5 μg IFN-β, significantly less loss of safranin O staining was observed, indicating inhibition of cartilage breakdown. Histologic analysis of cartilage in CIA in mice after 7 days of IFN-β therapy. Hind paw sections were stained with safranin O–fast green, which stains the cartilage proteoglycans. Sections were scored in a blinded manner on a 4-point scale as described in Materials and methods. Significantly less loss of safranin O staining was observed in the animals treated with IFN 2.5 μg than in controls (= 0.03), indicating inhibition of cartilage destruction. *Statistically significant difference.
