Objective To investigate the effect of cancer stem-like cells (CSCs) from osteosarcoma cell line on the polarization of macrophages.Methods CSCs were pre-treated with different doses of swainsonine and co-cultured with macrophages,and the phenotypic specific markers on macrophages were detected respectively.Results Compared to the control group,the expression of Arg-1 [(12.0 ± 3.1) % vs.(40.0±2.6)%,P<0.05] and interleukin (IL)-10 [(90.0±4.4) ng/Lvs.(150.0±6.8) ng/L,P <0.05] in macrophages co-cultured with CSCs pre-treated with swainsonine (1 mg/L) was decreased,whereas inducible nitric oxide synthase (iNOS) [(50.0 ±2.1)% vs.(12.0 ± 1.3)%,P<0.05] and tumor necrosis factor (TNF)-α [(240.0 ± 8.1) ng/L vs.(50.0 ± 3.3) ng/L,P < 0.05] increased.Conclusion Increased expression of beta-1,6-oligosaccharide in CSCs derived from osteosarcoma cell line induced the differentiation of bone marrow-derived macrophages into anti-inflammatory M2 macrophages.
