Blocking of sodium and potassium ion-dependent adenosine triphosphatase-α1 with ouabain and vanadate suppresses cell-cell fusion during RANKL-mediated osteoclastogenesis.

To examine the possible enrolment of Na(+)/K(+)-ATPase during osteoclast differentiation, Na(+)/K(+)-ATPase inhibitors, including ouabain and vanadate, were used in this study. These inhibitors significantly inhibited cell-cell fusion of RAW264.7 cells and bone marrow cells induced by RANKL.

Immobilized-OPG-Fc on a titanium surface inhibits RANKL-dependent osteoclast differentiation in vitro.

The purpose of the present study was to examine the effect of osteoprotegerin (OPG)-Fc fusion protein immobilized on a titanium surface on the initial differentiation of osteoclast precursor RAW264.7 cells. These cells were cultured on titanium specimens over which OPG-Fc was immobilized.

Titanium surface roughness accelerates RANKL-dependent differentiation in the osteoclast precursor cell line, RAW264.7.

The present study was a molecular analysis of the initial differentiation of osteoclast precursor RAW264.7 cells on titanium specimens. RAW264.
