Abstract
Hepatic veno-occlusive disease (HVOD) characterized by endothelial cell dysfunction is one of the serious complications after hematopoietic stem-cell transplantation or chemotherapeutic drug application. The mortality of HVOD patients with multiorgan dysfunction is as high as 80%. The primary aim of this study was to evaluate whether the infusion of human umbilical cord-derived endothelial colony forming cells (hUC-ECFCs) could mitigate HVOD injury and investigate the underlying mechanism. We found that the expression of chemokine C-X-C chemokine ligand 12 (CXCL12) was markedly increased in the livers of HVOD mice. Meanwhile, hUC-ECFCs infusion could significantly ameliorate liver injury in HVOD mice, which was accompanied by hUC-ECFCs recruitment in the liver, reduced liver pathological alterations, and decreased serum alanine aminotransferase and aspartate aminotransferase activity. Besides, CXCL12-induced migration in hUC-ECFCs was partly impeded by chemokine receptor type 7 (CXCR7) silence or CXCR4 blockage. In conclusion, our results demonstrated that hUC-ECFCs could mitigate HVOD through homing to the injured liver via the CXCL12-CXCR4/CXCR7 signaling pathway.

[PMID: 32021937 PMCID: PMC6994503 DOI: 10.1016/j.heliyon.2020.e03277] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2019] [Revised: 10/30/2019] [Accepted: 01/17/2020] [Indexed: 11/25/2022] Open
Abstract
Chaff (the outermost protective layer of rice grain) in nano and ground sized particles was bio-assessed to explore its insecticidal effects against the greater wax moth, Galleria mellonella (Lepidoptera: Pyralidae). These particles induced remarkable disturbances in the biological patterns of the greater wax moth. These were cleared as they exhibited insecticidal impact on both juvenile and adult stages, their impacts on larval, pupal and adult death, the formation of morphogenetic features (permanent larvae and larval-pupal intermediates), their negative influence on the adult emergence and the potentialities of the applied concentrations to hinder the larval weight gain. The recorded LC50 values proved more larvicidal potency of the nano-sized particle than that of the ground rice chaff one. The transverse sections in the midgut of the 20 days old larvae (both treated and untreated ones) confirmed the histopathological deformations of the examined particles. The high siliceous content of the chaff particle may be responsible for such recorded disturbances.
