CD68 immunostaining in the Im-B and Im-NS groups. CD68-positive cells were observed in both Im-B (a-c) and Im-NS groups (d-f). They were observed mainly in the synovial membrane of the Im-B group. After 8 weeks, there was a small difference in the number of CD68-positive cells between the two groups. F: Femur, S: Synovium, JS: Joint Space, M: Meniscus. The black arrowheads indicate CD68-positive cells. Scale bar = 100 μm
