Figure S1. TG2 expression is increased in synovial tissues in CIA. (A) Representative images (40× magnification) of synovial membrane/cartilage from articular tissue sections of control and arthritic rats at different times (18, 28, and 32 days) after immunization with type II collagen. Tissues were immunostained with TG2. (B, C) Graphs show relative labeling intensity calculated from six random fields for each tissue section in the (B) synovial membrane or in the (C) cartilage. Each column represents mean value ± SEM of total fields from two different tissue sections per individual rat (Ctl, n = 4; CIA, n = 8).
