Fig. 1. Analysis of synovitis in CCR5−/− and WT mice.
Enlargement of synovial lining cell layer and density of the cells were obtained from all four quadrants (medial tibia, medial femur, lateral tibia, and lateral femur). The evaluation areas were white four-sided figures which were between the bone (femur or tibia) and ligament. (A) medial side of the knee (B) lateral side of the knee. Magnification 40× (Scale bar = 500 µm). F = femur; T = tibia; L = ligament; LM = lateral meniscus; MM = medical meniscus.
