Abstract

Osteocytes embedded in bone have been postulated to orchestrate bone homeostasis by regulating both bone-forming osteoblasts and bone-resorbing osteoclasts. We find here that purified osteocytes express a much higher amount of receptor activator of nuclear factor-κB ligand (RANKL) and have a greater capacity to support osteoclastogenesis in vitro than osteoblasts and bone marrow stromal cells. Furthermore, the severe osteopetrotic phenotype that we observe in mice lacking RANKL specifically in osteocytes indicates that osteocytes are the major source of RANKL in bone remodeling in vivo.

Claims other papers make about this one

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

  • In the initiation phase, under RANKL and M-CSF, hematopoietic stem cells are recruited to specific bone surface areas and differentiate into mature osteoclasts that initiate bone resorption.

    “In the initiation phase, under the action of osteoclastogenic factors including RANKL and M-CSF, hematopoietic stem cells are recruited to specific bone surface areas and differentiate into mature osteoclasts that initiate bone resorption [167, 168].”
  • Osteocytes act as the main source of RANKL to promote osteoclastogenesis.

    “There is evidence that osteocytes act as the main source of RANKL to promote osteoclastogenesis [167, 168], although this factor has also been demonstrated to be produced by other cell types such as stromal cells [194], osteoblasts, and fibroblasts [88, 89].”
  • Conditional deletion of RANKL expression in osteocytes using a DMP1 promoter caused a severe osteopetrotic phenotype.

    “In 2011, Nakashima et al.51 showed that the conditional deletion of RANKL expression in osteocytes using a DMP1 promoter caused a severe osteopetrotic phenotype.”
  • Osteoclast fusion requires RANKL, which is highly expressed by BLCs, osteoblasts in the growing skeleton, and osteocyte arborizations that reach the bone surface in adults.

    “Fusion also requires RANKL, which is highly expressed by BLCs;161 osteoblasts in the growing skeleton; and osteocyte arborizations that reach the bone surface in adults.51,52”

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.
