Macrophages, the cells of the innate immune system, play a key role in all three types of xenograft rejection. However, the mechanism underlying their direct effects is incompletely understood. To study the direct effects of macrophages, established human model system combined the U937 monocyte cell line and mini-pig adipose derived mesenchymal stem cells (mp AD-MSCs). Treatment of mp AD-MSCs with macrophage secretion medium (Macro SM) markedly reduced the cell viability, increased lactate dehydrogenase release, and induced apoptotic cell death. The proteomic analysis identified 17 proteins in Macro SM. Based on the gene ontology analysis tool, matrix metalloproteinase (MMP)-9 was selected as the protein affecting MSC viability. To confirm the effect of MMP-9, cells were treated with recombinant human MMP-9 that resulted in decreased cell viability and increased lactate dehydrogenase release. These results suggest that MMP-9 may decrease the cell viability by damaging the cell membrane in the co-culture model.
