Abstract

To better understand the complex roles of transforming growth factor‐beta (TGF‐β) in bone metabolism, we examined the impact of a range of TGF‐β concentrations on osteoclast differentiation. In co‐cultures of support cells and spleen or marrow osteoclast precursors, low TGF‐β concentrations stimulated while high concentrations inhibited differentiation. We investigated the influences of TGF‐β on macrophage colony stimulating factor (M‐CSF), receptor activator of NF‐κB ligand (RANKL), and osteoprotegerin (OPG) expression and found a dose dependent inhibition of M‐CSF expression. RANKL expression was elevated at low TGF‐β concentrations with a less dramatic increase in OPG. Addition of OPG blocked differentiation at the stimulatory TGF‐β dose. Thus, low TGF‐β concentrations elevated the RANKL/OPG ratio while high concentrations did not, supporting that, at low TGF‐β concentrations, there is sufficient M‐CSF and a high RANKL/OPG ratio to stimulate differentiation. At high TGF‐β concentrations, the RANKL/OPG ratio and M‐CSF expression were both repressed and there was no differentiation. We examined whether TGF‐β‐mediated repression of osteoclasts differentiation is due to these changes by adding M‐CSF and/or RANKL and did not observe any impact on differentiation repression. We studied direct TGF‐β impacts on osteoclast precursors by culturing spleen or marrow cells with M‐CSF and RANKL. TGF‐β treatment dose‐dependently stimulated osteoclast differentiation. These data indicate that low TGF‐β levels stimulate osteoclast differentiation by impacting the RANKL/OPG ratio while high TGF‐β levels repress osteoclast differentiation by multiple avenues including mechanisms independent of the RANKL/OPG ratio or M‐CSF expression regulation. © 2004 Wiley‐Liss, Inc.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Different concentrations of TGF-β have different effects on the RANKL/OPG ratio and osteoclast differentiation: low concentrations increase stimulation of osteoclast differentiation, while high concentrations have the opposite effect.

    “Different concentrations of TGF-β have different effects on the RANKL/OPG ratio and ultimately on osteoclast differentiation (low concentrations of TGF-β increase the stimulation of osteoclast differentiation, while high concentrations of TGF-β have the opposite effect) [98, 99].”

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.
