Bone-marrow mesenchymal stem cells (MSCs) are the origin of bone-forming cells with immunomodulation potential. Among the generated immunosuppressive molecules there is HLA-G5. HLA-G proteins play a crucial role in promoting the acceptance of allografts. However, the mechanisms regulating the expression of HLA-G5 in human MSCs are unknown. We induced differentiation of human MSCs (harvested from iliac crests of healthy volunteers after their informed consent following approved...
