Abstract: The aim of this study was to explore the efficacy of adipose-derived mesenchymal stem cells condition medium (ADSCs-CM) on the inflammatory response of liver ischemia reperfusion combined with partial hepatectomy in miniature pigs. Based on the laparoscopic technique, a model of liver ischemia reperfusion (IR) combined with partial hepatectomy was established in 24 miniature pigs. Miniature pigs were divided into four groups:model group (IRI), DMEM group (DMEM), ADSCs-CM group (CM) and ADSCs group (ADSCs), with six pigs in each group, according to the four different substances namely physiological saline, concentrated basal medium, concentrated ADSCs-CM, ADSCs transplanted to the liver after surgery. The blood and liver tissue samples were harvested pre-operation, 1 day, 3 days, and 7 days after operation. The effect of ADSCs-CM on inflammation were comprehensively evaluated through histopathological inflammatory cell observation, blood indicators detection, serum cortisol (COR), C-reactive protein (CRP) and hyaluronic acid (HA) detection of ELISA, liver tissue inflammation-related IL-1β, IL-6, TNF-α, IL-10 mRNA detection of qRT-PCR. The results found that 1 and 3 days after the operation:there were more inflammatory cells in the pathological tissue sections of the IRI group and DMEM group. The results of blood routine and inflammation-related genes also showed that there was obvious inflammation after the operation. The ADSCs-CM and ADSCs treatment groups significantly reduced the infiltration of inflammatory cells in the tissues and the number of white blood cells (WBC), neutrophils (NE) and lymphocytes (LY) in the blood, and decreased the expression levels of pro-inflammatory factor IL-1β, IL-6, TNF-α mRNA in tissues, and increased the expression level of anti-inflammatory factor IL-10 mRNA. After 7 days, each group basically recovered to the pre-operation. The results showed that liver ischemia-reperfusion combined with partial hepatectomy can cause inflammation, and both ADSCs-CM and ADSCs improved the inflammatory response of liver ischemia-reperfusion combined with partial hepatectomy. Transplantation of ADSCs-CM has the potential to become a cell-free therapy for the treatment of inflammation in the future.
