OCPs in PBMCs of PsA patients. PBMCs were obtained from PsA patients and healthy controls and cultured in the absence (a and b) or presence (c and d) of MCSF (25 ng/ml) and RANKL (100 ng/ml) for 14 days, fixed and stained for TRAP, and photographed at ×10 magnification. Numbers in parentheses represent the total number of osteoclasts per 10⁶ PBMCs for each sample.
