Abstract

Summary. The new members of the tumour necrosis factor (TNF) receptor‐ligand family, receptor activator of nuclear factor‐κB ligand (RANKL) and its receptor RANK, play a crucial role in osteoclast differentiation and activation. An increased expression of RANKL and/or RANK may be involved in the excessive bone resorption observed in multiple myeloma (MM). We used immunohistochemistry to study RANK and RANKL expression in bone marrow (BM) biopsies obtained at diagnosis in 15 MM patients, six patients with monoclonal gammopathy of undetermined significance (MGUS) and 10 normal BM biopsies. Plasma cells were not labelled with anti‐RANKL or anti‐RANK antibodies. In all biopsies, RANKL was expressed in endosteal bone surface, around vessels and in cells characterized by cytoplasmic expansions. These last cells did not express CD45 and were vimentin positive, corresponding to bone marrow stromal cells. Numerous stromal cells expressed RANKL in MM and MGUS specimens, with a greater expression in MM than in MGUS. Very few cells were stained with anti‐RANKL in normal BM specimens. With the anti‐RANK antibody, small mononuclear cells in the bone microenvironment were positive and were identified as erythroblast cells. In conclusion, we showed that RANKL was expressed in reticular stromal cells, with a greater intensity in myeloma specimens. These results suggest that RANKL overexpressed by bone marrow stromal cells may contribute to the high rate of bone resorption observed in MM.

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.
