Fig. 6. αSMA and type III collagen (but not type I) expression are increased in human OA cartilage.

Fig. 6

a Representative picture of IHC analysis of cartilage section from human hip fracture, OA hip and OA knee stained with anti-αSMA antibody. Analysis was done on several patients: the percentage of αSMA positive cells was significantly increased in OA hip (n = 4) and OA knee (n = 5) compared to hip fracture (n = 6). (ANOVA tests: **p < 0.01). b Representative picture of IHC analysis of cartilage section from human hip fracture, OA hip and OA knee stained with anti-type I collagen antibody. Analysis was done on several patients: the percentage of type I collagen positive cells was not significantly different in OA hip (n = 8) and OA knee (n = 8) compared to hip fracture (n = 8). (ANOVA tests: not significant for both comparisons). c Representative picture of IHC analysis of cartilage section from human hip fracture, OA hip and OA knee stained with anti-type III collagen antibody. Analysis was done on several patients: the percentage of type III collagen positive cells was significantly increased in OA hip (n = 15) and OA knee (n = 7) compared to hip fracture (n = 8). (Error bar: SED, ANOVA tests: *p < 0.05, ***p < 0.001)
