| Abstract: | This study aimed to investigate the distinctive roles of the monocytes and macrophages on osteogenic differentiation of adipose-derived mesenchymal stromal cells (ADMSCs) in 3D spheroid co-cultures. We hypothesized that monocytes or macrophages (subtypes pro-inflammatory M1 and pro-wound healing M2) would affect the osteogenic differentiation of ADMSCs in 3D spheroids and that cell–cell interactions between monocytes/macrophages and ADMSCs play an important role in the osteogenic differentiation process of ADMSCs. The obtained results indicated that the osteogenic differentiation of ADMSCs was inhibited by monocytes and both macrophage subtypes in 3D spheroids. Monocytes and M2 macrophages had a stronger inhibiting effect than M1 macrophages. Cell-cell interactions mediated by N-cadherin likely played a role in the inhibiting effect of monocytes/macrophages on the osteogenic differentiation of ADMSCs. |
