Pre-administration of human umbilical cord mesenchymal stem cells has better therapeutic efficacy in rats with D-galactosamine-induced acute liver failure
Copyright © 2024. Published by Elsevier B.V..
BACKGROUND: Acute liver failure (ALF) is characterized by an intense systemic inflammatory response, single or multiple organ system failure and high mortality. However, specific and effective treatments for ALF patients are still lacking. According to the current investigation, human umbilical cord mesenchymal stem cells (hUCMSCs) have shown remarkable potential to enhance the functional recovery of injured livers. We aimed to investigate the therapeutic effects of time-differentiated hUCMSCs administration regimens on ALF.
METHODS: The rat model of ALF was induced by D-galactosamine (D-gal), and hUCMSCs were administered via the tail vein 12 h before or 2 h after induction. The potential mechanisms of hUCMSCs in treatment of ALF, regulation cell subset and secretion of inflammatory factors, were verified by co-culturing with PBMCs in vitro. Liver function indicators were detected by an automatic biochemistry analyzer and inflammatory factors were obtained by ELISA detection. The distribution of hUCMSCs in rats after administration was followed by quantitative real-time fluorescence PCR.
RESULTS: The findings of the study discovered that administration of hUCMSCs 12 h prior to surgery could significantly improve the survival rate of rats, stabilize various liver function indicators in serum levels of ALT, AST, T-BIL, or ALB diminish inflammatory infiltration in liver tissue, and inhibit the secretion of inflammatory factors.
CONCLUSION: Our data showed that pre-transplantation of hUCMSCs had a better therapeutic effect on ALF rats, providing empirical evidence for preclinical studies. Thus, the timing of hUCMSCs transplantation is necessary for the optimal clinical treatment effect.
