OSCAR and OPG expression by BMECs. BMECs were cultured in the absence (A and D) or presence of 5 ng/mL IL-1β, (B, E) and 5 ng/mL TNF-α (C, F) for 40 hours and fixed for visualization by con-focal microscopy. OSCAR is seen as green (A, B, C) and OPG as red (D, E, F). Original magnification was 200X.
