Table 1 Joint inflammation and cartilage damage on day 3 of antigen-induced arthritis

From: Syndecan-3 is selectively pro-inflammatory in the joint and contributes to antigen-induced arthritis in mice

  1. Synovial hyperplasia of the lining layer, synovial infiltration of the sublining by leukocytes, exudate in the joint cavity, and loss of proteoglycan from the articular cartilage were observed in haematoxylin/eosin and haematoxylin/safrinin-O-stained sections. Sections were scored blind by two independent observers from 0 to 3 (hyperplasia, exudate and cartilage depletion) or 0 to 5 (infiltrate). The arthritis index is the sum of all observations. *P <0.05 and **P <0.01 of the parameter compared to wild-type mice using Mann-Whitney U test.
