Popis: Emerging evidence has indicated that mesenchymal stem cells (MSCs) are involved in the modulation of inflammation. Human placenta-derived (HPL)-MSCs exist in sufficient quantities and play a role in immune regulation. However, the exact roles of HPL-MSCs in inflammation and the specific underlying mechanisms are not well defined. In the present study, HPL-MSCs were obtained from human fetal placentas, and further purified using a commercial kit. Using ELISA, reverse transcription-quantitative PCR, western blot, NO detection and other assays, the present study revealed that HPL-MSCs may improve lipopolysaccharide-induced macrophage inflammation by regulating macrophage polarization. Further mechanistic studies demonstrated that HPL-MSCs attenuated the NF-κB signaling pathway by regulating the expression of toll-like receptor 4 and the phosphorylation of IκBα and p65, which resulted in a reduction in the levels of inflammation. The present study indicated that HPL-MSCs may act as a novel target for the treatment of inflammation-related diseases.
