摘要 BACKGROUND:Adipose-derived stem cells(ADSCs) are particularly attractive in future clinical applications of stem cell-based therapy for acute-on-chronic liver failure(ACLF) This study was undertaken to evaluate the therapeutic potential of ADSCs on ACLF.METHODS:ADSCs isolated from porcine fat tissue were expanded and labeled with BrdU.Rabbit models of ACLF were created by administration of D-Gal following CCl 4-induced cirrhosis.One day after administration of D-Gal,rabbits of the ACLF/ADSCs group(n=15) were received ADSCs transplantation,while those in the ACLF/saline group(n=15) were treated with the same volume of saline.Biochemical parameters and histomorphological scoring were evaluated;the distribution and characteristics of transplanted ADSCs as well as the pathology of the liver were examined.RESULTS:ADSCs transplantation improved the survival rate and the liver function of rabbits with ACLF.Biochemical parameters of the ACLF/ADSCs group were improved compared with those of the ACLF/saline group,and histomorphological scoring of the ACLF/ADSCs group was significantly lower than that of the ACLF/saline group.ADSCs were identified in the periportal region of the liver after cell transplantation.CONCLUSION:Xenogenic ADSCs have therapeutic efficacy in the ACLF rabbit model.
