Module 8: Figure osteoclast Ca2+ oscillations
Osteoclast precursor cell Ca2+ signalling.
Wild-type (WT) osteocyte precursor cells that have been stimulated with receptor activator of nuclear factor κB (NF-κB) ligand (RANKL) and colony-stimulating factor-1 (CSF-1) display oscillatory Ca2+ signals. Such oscillations are completely absent in cells from mice, where the adaptor protein DNAX-activating protein 12 (DAP12) has been knocked out (DAP12−/−).
