Kupffer cells-dependent inflammation in the injured liver increases recruitment of mesenchymal stem cells in aging mice
نویسندگان
چکیده
Mesenchymal stem cells (MSCs) repair tissue injury and may be used to treat immune associated diseases. In carbon tetrachloride (CCl4)-induced liver injury murine model, we administered MSCs. When MSCs were transmitted to young and old mice with liver injury, more MSCs were recruited in old mice. In old mice, inflammation, characterized by TNF-α and IL-6, was increased due to hyper-activation and hyper-function of Kupffer cells. Blocking Kupffer cells decreased MSCs migration in old mice. In vitro, Kupffer cells isolated from old mice secreted more inflammatory cytokines and chemokines. Thus, hyper-activation of Kupffer cells in old mice increased recruitment of MSCs after their therapeutic administration.

متن کاملH2O2-Preconditioned Umbilical Cord-Derived Mesenchymal Stem Cells Ameliorate Liver Regeneration in Acute Liver Failure-Induced Mice
Introduction: Mesenchymal stem cells (MSCs) are suitable candidates for the treatment of liver diseases. However, their low survival rate limits their efficacy following transplantation. This study aimed to evaluate the therapeutic potentials of H2O2-preconditioned umbilical cord-derived MSCs (UCMSCs) on acute liver failure (ALF) in mice. Methods: UCMSCs were pre-conditioned with different con...

Background: Mesenchymal stem cells (MSCs) have been recently received increasing attention for cell-based therapy, especially in regenerative medicine. However, the low survival rate of these cells restricts their therapeutic applications. It is hypothesized that autophagy might play an important role in cellular homeostasis and survival. This study aims to investigate the regenerative potentia...
متن کاملThe protective effect of bone marrow-derived mesenchymal stem cells in liver ischemia/reperfusion injury via down-regulation of miR-370
Objective(s): Liver transplantation is the most important therapy for end-stage liver disease and ischemia reperfusion (I/R) injury is indeed a risk factor for hepatic failure after grafting. The role of miRNAs in I/R is not completely understood. The aim of this study was to investigate the potential protective role of the mesenchymal stem cells (MSCs) and ischemic pr...
