Cell culture

Sorted primary CD115(+) precursors were cultured in α-minimal essential medium (MEM) containing 10% FBS,1% penicillin-streptomycin solution and 50 ng ml? 1 colony stimulating factor (M-CSF, Abcam). After 3 days,the medium was replaced with fresh medium. LA was added at a concentration of 100 μg/ml to stimulate the precursors. To inhibit the expression of Cadherin-11, the primary osteoclast precursors were transfected with Cadherin-11 siRNA using INVI DNA RNA Transfection reagent (Invigentech)for 24h. The sequence of Cadherin-11 siRNA was CCAATGGACCAAGATTTAT. In some experiments, primary cells were treated with BYL719 (2.5 μM), GSK690693 (25 nM), 666–15 (50 nM), rapamycin (20 μM), or AMG-487 (30 μM).
