Fig.5 Clinical score of joint swelling hTNFα mice (male, 5-6wks, n=10).

Signs of arthritis were assessed by a visual score where 0 = Normal paw, 1 = one toe inflamed or swollen, 2 = more than one toe, but not entire paw, or mild swelling of the entire paw, 3 = entire paw inflamed and swollen, and 4 = very inflamed and swollen paw or ankylosed paw.

Fig.8 Score of hTNFα-Tgmice (A) and H&E pathology(B). (male)

Compared with the WT C57BL/6, the mixed inflammatory cell infiltration in hTNFα-Tg mice is significantly increased, with obvious proliferation of synovial joints, formation of pannus, fibroblast tissue production, and cartilage erosion.
