Xenotransplantation is a promising alternative to overcome donor shortage in transplantation. CD40 molecule plays an important role in the interaction of T cells with antigen-presenting cells and in the activation of vascular endothelial cells. We investigated whether the xenogeneic interaction between human CD40L (hCD40L) on T cells and porcine endothelial(More)
Stem cells are useful for cell replacement therapy. Stem cell differentiation must be monitored thoroughly and precisely prior to transplantation. In this study we evaluated the usefulness of electric cell-substrate impedance sensing (ECIS) for in vitro real-time monitoring of neural differentiation of human mesenchymal stem cells (hMSCs). We cultured hMSCs(More)
To elucidate the potential role of porcine RANTES (Regulated upon Activation Normal T cells Expressed and Secreted) in xenograft rejection, we investigated its chemotactic activity for human mononuclear cells, as well as the effect of human cytokines on its expression in porcine endothelial cells. Porcine RANTES cDNA was successfully cloned from aortic(More)
Pig endothelial cells are the first cells to interact with human immune components after organ xenotransplantation, which is a procedure currently considered to be the best treatment option for end-stage organ failure. It is, therefore, essential to study the mechanisms of molecular interaction between pig endothelial cells and human immune components, in(More)
We investigated TLR10 expression in human monocytes, THP-1 cells, cultured in hypoxia (3% O(2)). Levels of both TLR10 mRNA and protein in THP-1 cells cultured in hypoxia were significantly higher than those cultured in normoxia (20% O(2)). We examined intracellular reactive oxygen species (ROS) content in hypoxic cells, and TLR10 expression in cells treated(More)
