Title: Transcription profiling by array of human dendritic cells exposed to mesenchymal stem cells      
dateReleased:
12-31-2010
description:
All experiments are performed on human dendritic cells (DCs) differentiated in GM-CSF and IL-4 from CD14+ cells and bone marrow mesenchimal stem cells (MSCs). We found that MSCs impair active immune synapse formation and we evidenced at electron microscopy two types of contact between MSCs and DCs: gap and adherent junctions. In the same experiments we show that MSC contacts induce a reorganization of DC cytoskeleton by the formation of actin podosomes, structures typical of an immature, tolerogenic state of DCs. These results suggest that MSCs exert a tolerogenic effect on DCs by mechanism mediated by cell-cell contact. This induces DC cytoskeleton reorganization with formation of actin podosomes.
