Summary Cells obtained from surgical bone specimens of eight patients with Paget’s disease of bone were maintained in culture for up to 8 months and seven passages. The doubling time during the period of maximal cell growth ranged from 4 to 12 days. Evidence consistent with the hypothesis that many of the cells were bone cells included the following: (a) histochemical techniques demonstrated staining of some cells for alkaline phosphatase or acid phosphatase and succinic dehydrogenase; (b) parathyroid extract stimulated increased uptake of3H-thymidine and3H-uridine; (c) parathyroid extract suppressed and salmon calcitonin stimulated uptake of3H-proline; and (d) crystalline calcium deposits were found within cells and extracellularly. Ultrastructural analysis revealed that three of the eight cultures contained cells whose nuclei had inclusions which were almost identical to those found in the osteoclast nuclei of all patients with Paget’s disease. The maintenance of cells derived from pagetic bone in long-term culture should aid in testing the hypothesis that Paget’s disease represents a slow virus infection of bone.
