Abstract

Conditioned media (CM) from mesenchymal stem cells (MSCs) contains various cytokines, growth factors and microRNAs, which may serve important roles in modulating the inflammatory process. However, the effect of MSC‑CM on inflammatory bone loss remains unknown. The present study investigated the effects of conditioned media from human adipose‑derived mesenchymal stem cells (AMSC‑CM) on the prevention of lipopolysaccharide (LPS)‑mediated bone loss in mice. To investigate the underlying mechanisms of this effect, the effects of AMSC‑CM on serum levels of inflammation‑associated cytokines [tumor necrosis factor (TNF)‑α, interleukin (IL)‑1, IL‑6 and IL‑10] in LPS‑treated mice, in addition to their mRNA expression in LPS‑treated macrophages, was investigated. Micro‑computed tomography and histological analysis revealed that AMSC‑CM administration effectively inhibited LPS‑induced bone destruction in vivo. ELISA analysis indicated that AMSC‑CM significantly reduced the serum levels of proinflammatory cytokines (TNF‑α, IL‑1 and IL‑6) in LPS‑treated mice. Furthermore, AMSC‑CM treatment significantly decreased the mRNA expression levels of TNF‑α, IL‑1 and IL‑6 in macrophages treated with LPS. These findings indicate that AMSC‑CM inhibits LPS‑induced bone loss by decreasing the production of proinflammatory cytokines, suggesting that the use of AMSC‑CM may be a potential therapeutic strategy for the treatment of inflammatory bone loss.
