In order to evaluate the usefulness of a recently described acid ATPase as a marker for osteoclast differentiation, we have performed histochemical and biochemical analyses of the distribution of tartrate-resistant acid phosphatase (TRAP) and tartrate-resistant acid ATPase (TrATPase) in bone, bone marrow and spleen. Histochemical studies of bone demonstrated that multinucleated osteoclasts stained for both TRAP and TrATPase. However, staining for TRAP covered the entire cytoplasm, whereas TrATPase staining was localized primarily to cytoplasmic areas next to bone and on adjacent mineralized surfaces. Occasionally TrATPase-positive mononuclear cells were observed on excavations in the bone surface. In the spleen, mononuclear TRAP-positive cells were located in the marginal zone between the white and red pulp, whereas no staining for TrATPase was observed. Comparison of the biochemically measured TRAP and TrATPase activities showed that bone had the highest specific activity for both enzymes followed by the bone marrow and spleen. However, enzyme activity in the spleen compared to bone was about 4-fold higher for TRAP compared to TrATPase. Additional evidence for a restricted expression of TrATPase to bone relative to spleen was obtained by in vitro translation studies. These data indicate that TrATPase is a more selective marker than TRAP in histochemical and biochemical studies of osteoclast differentiation and furthermore suggest that development of TrATPase is a late acquisition in osteoclast ontogeny.
