ED-1 staining on the lateral tibial surface. a Uninjected left knee. Arrow identifies normal background level of ED-1-positive macrophages in synovium. b PBS injections at Days 7, 14, and 21 in the right knee. Arrow identifies ED-1-positive macrophages surrounding degenerating cartilage fragment in synovium. There is a mild increase over normal background levels, likely as a result of the disease process (rather than the treatments). c IA-BioHA injections (0.5 mg/rat) at Days 7, 14, and 21 in the right knee. Arrow identifies ED-1-positive macrophages in synovium. There is a mild increase over normal background levels, likely as a result of the disease process. Images were acquired at 400x magnification
