Human Bone Marrow Mesenchymal Stromal Cells Attenuate Tissue Injury and Reduce Inflammation in Experimental Acute Pancreatitis
Acute pancreatitis (AP) which is distinguished by local pancreatic necrosis, following by systemic organ failure is known as an inflammatory disease. Up to now, there are only a few treatment options accessible for patients suffering from AP. In this study, we aimed to examine the anti-inflammatory capacities of human bone marrow-derived mesenchymal stromal cells (hBM-MSC) in a detailed AP model experiment.
AP was induced in C57BL/6 mice by intraperitoneal administration of cerulein (100 µg/kg/h × 7 doses) at intervals of 1 hour (h). Then, 2×105 MSCs were infused in the AP mice by tail vein 6 h after the last cerulein injection. Mice were sacrificed 12 h following the injection of hBM-MSC, and blood samples and pancreas tissues were obtained.
We first determined the presence of transplanted hBM-MSC in the pancreas of mice with AP, but not the control mice. Our data indicate that administration of hBM-MSCs to mice with AP lead to (i) decreased serum levels of amylase, lipase and myeloperoxidase activities, (ii) downregulation of proinflammatory cytokine, macrophage inflammatory protein 2 (MIP-2), and (iii) upregulation of the anti-inflammatory cytokine, interleukin 10 (IL-10). Moreover, hBM-MSC administration results in notably attenuated cerulein-induced histopathological alternations and edema.
we demonstrate that hBM-MSC attenuates AP signs and indicating that hMB-MSC therapy could be a suitable approach for the treatment of inflammatory disease such as AP.
