PG - 149-155 LID - S0006-291X(22)00460-0 [pii] LID - 10.1016/j.bbrc.2022.03.115 [doi] AB - The coupling of bone resorption and bone formation is well-recognized in the bone remodeling process, in which osteoblasts and osteoclasts are key players. However, the anabolic effect of human primary osteoclasts has rarely been reported as mouse and cell line derived osteoclasts were mostly used in previous reports. Therefore, a comprehensive comparison of mouse and human osteoclasts and their corresponding functions is needed to study cell-cell interactions between osteoclasts and osteoblasts. Osteoclasts from mouse and human origin were generated, characterized and compared, after which their anabolic effects on the osteogenic differentiation of mouse and human MSCs were assessed. Both murine RAW264.7 derived osteoclasts (mOCs) and primary human osteoclasts (hOCs) derived from buffy coats characteristically displayed multinuclearity, marked integrin beta3 expression and enhanced TRAP activity. Despite comparable cell size, mOCs showed higher osteoclast density (number of osteoclasts per cm(2) culture dish) and osteoclast nuclearity (average number of nuclei per osteoclast), but lower TRAP activity compared to hOCs. Culturing primary rat and human bone marrow MSCs with the conditioned medium of mOCs or hOCs showed anabolic effects regarding the osteogenic differentiation of MSCs with superiority of hOCs over mOCs. We conclude that despite morphological and functional differences between mouse and human osteoclasts, their secretory factors evoke similar anabolic effects on MSC osteogenic differentiation.
