ACP5 and ocular melanoma: Therefore, in our previous study, we systemically investigated and demonstrated differences of osteoclast profiles of MRONJ (BP), OM and ORN regarding osteoclast morphology, quantity, and the expression of the osteoclastic effectors dendritic cell-specific transmembrane protein (DC-STAMP) (associated to cell–cell fusion) and tartrate-resistant acid phosphatase (TRAP) (associated with osteoclastic bone resorption) [12].
