Abstract

After our previous report that osteoclast-like multinucleated cells (MNCs) were formed in response to 1 alpha,25-dihydroxyvitamin D3 [1 alpha,25-(OH)2D3] in cocultures of mouse spleen cells and osteoblast-rich populations freshly isolated from fetal mouse calvariae, we examined whether such primary osteoblast-like cells can be replaced by established cell lines in inducing osteoclast-like cell formation. We first used two clonal cell lines simultaneously established from newborn mouse calvariae. One was the osteoblastic cell line MC3T3-E1, and the other was the preadipose cell line MC3T3-G2/PA6. Tartrate-resistant acid phosphatase (TRACP; a marker enzyme of osteoclasts)-positive mononuclear cells and MNCs were formed in the cocultures of spleen cells and MC3T3-G2/PA6 cells in the presence of 1 alpha,25-(OH)2D3. Dexamethasone greatly potentiated TRACP-positive MNC formation induced by 1 alpha,25-(OH)2D3, whereas the glucocorticoid alone had no effect on it. In contrast, osteoblastic MC3T3-E1 cells failed to induce TRACP-positive cells in the cocultures. Another bone marrow-derived stromal cell line ST2 also induced TRACP-positive MNC formation in the cocultures in response to 1 alpha,25-(OH)2D3 and dexamethasone. Salmon calcitonin enhanced cAMP production in the cocultures only when TRACP-positive cells were formed. Autoradiographic studies demonstrated that [125I]calcitonin specifically bound to TRACP-positive cells formed in the cocultures. When spleen cells and either MC3T3-G2/PA6 or ST2 cells were cocultured on sperm whale dentine slices in the presence of 1 alpha,25-(OH)2D3 and dexamethasone, numerous resorption lacunae were formed. These results show that the two bone marrow-derived stromal cell lines can support osteoclast-like cell differentiation in cocultures with spleen cells.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
