Transmigration: A New Property of Mature Multinucleated Osteoclasts
Open accessAbstract
Even though it is assumed that multinucleated osteoclasts are migrating cells on the bone surface to be resorbed, we show that they can also selectively transmigrate through layers of cells usually found in the bone microenvironment. This activity is associated with c-src and MMPs and can be stimulated by bone metastatic breast cancer cells, a process blocked by bisphosphonate treatment. Introduction: Osteoclasts have an hematopoietic origin and are bone-resorbing cells. Monocytic precursors migrate to the bone surface where they fuse to form multinucleated osteoclasts able to migrate over the bone surface. We studied whether multinucleated osteoclasts were also able to transmigrate through tissues. Materials and Methods: Murine spleen-derived and green fluorescent protein (GFP)-Raw derived osteoclasts were seeded on osteoblasts and several other cell types. The cells were fixed for 20 minutes, 4 or 12 h after osteoclast seeding, and stained with phalloidin to visualize actin using confocal microscopy. Drugs such as PP2 and GM6001, inhibitors of c-src and matrix metalloproteinases (MMPs), respectively, and risedronate were used to determine osteoclast transmigration regulating factors. Results: We observed by confocal microscopy that multinucleated osteoclasts specifically transmigrate through confluent layers of various cell types present in the bone microenvironment in vitro. This is an efficient process associated with c-src and MMPs but is independent of podosomes. Moreover, conditioned medium from bone metastatic breast cancer cells stimulates osteoclast transmigration in vitro, a process inhibited by bisphosphonate treatment. Conclusions: Our data describe a new property of mature multinucleated osteoclasts to transmigrate through various cell types. The ability to control this highly regulated osteoclast transmigration process may offer new therapeutic strategies for bone diseases associated with an imbalance in bone remodeling caused by excessive osteoclast resorption.

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.
