Very low concentrations of S1P are chemotactic for osteoclast precursors, even though large concentrations inhibit their motion seventy nine. This means that these precursors, which express both of those S1PR1 and S1PR2, are retained inside the vicinity from the bone via the S1P gradient: S1PR2 prevents S1PR1-induced migration of those bone-resorbi
