Mesenchymal stem cells (MSC) modulate the macrophage-mediated inflammatory
response through the secretion of soluble factors. In addition to its classical
effects on calcium homeostasis, 1,25-dihydroxyvitamin D3 (1,25D3) has emerged as
an important regulator of the immune system. The present study investigates
whether 1,25D3 modulates the paracrine interactions between MSC and macrophages.
1,25D3 stimulated MSC to produce PGE(2) and VEGF and regulated the interplay
between macrophages and MSC toward reduced pro-inflammatory cytokine production.
Conditioned media (CM) from co-cultures of macrophages and MSC impaired MSC
osteogenesis. However, MSC cultured in CM from 1,25D3-treated co-cultures showed
increased matrix maturation and mineralization. Co-culturing MSC with macrophages
prevented the 1,25D3-induced increase in RANKL levels, which correlated with
up-regulation of OPG secretion. MSC seeding in three-dimensional (3D) substrates
potentiated their immunomodulatory effects on macrophages. Exposure of 3D
co-cultures to 1,25D3 further reduced the levels of soluble factors related to
inflammation and chemotaxis. As a consequence of 1,25D3 treatment, the
recruitment of monocytes toward CM of 3D co-cultures decreased, while the
osteogenic maturation of MSC increased. These data add new insights into the
pleiotropic effects of 1,25D3 on the crosstalk between MSC and macrophages and
highlight the role of the hormone in bone regeneration.
