    Abstract:
    Cells harvested from human giant cell tumours of bone were characterized on the basis of morphological features, proliferative capacity, total(AP) and tartrate resistant acid phosphatase (TRAP) activity, and hormonal response. Culture were formed by mononucleated and multinucleated cells. Mononucleated cells showed fibroblastic morphology, whereas multinucleated cells showed osteoclastic phenotype. We conclude that in these cultures mature osteoclasts and their mononuclear precursors are present.
