Abstract: To explore the oxidative stress response of adipose-derived mesenchymal stem cells-conditioned medium (ADSCs-CM) on liver injury in miniature pigs. In this experiment, 24 healthy miniature pigs were selected and randomly divided into four groups, namely model group (IRI), DMEM control group (DMEM), ADSCs-CM treatment group (CM) and ADSCs treatment Groups (ADSCs), six pigs each group. All four groups, laparoscopic techniques were used to establish the liver injury model of miniature pigs with ischemia reperfusion (IR) combined with partial hepatectomy. The pigs in the IRI group were transplanted with normal saline, the pigs in the DMEM group were transplanted with concentrated basal medium, and the pigs in the CM group were transplanted with concentrated adipose-derived stem cell culture medium, the pigs in the ADSCs group were transplanted with adipose stem cells. Blood and liver tissue samples were collected in each group before the operation, 1 day, 3 days and 7 days after the operation. Use liver function test kit to detect total bilirubin (T-BIL), lactate dehydrogenase (LDH), and total protein (TP) in sera; use oxidation reaction kit to detect malondialdehyde (MDA), intramedullary peroxidase (MPO), superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase in liver tissue (GSH-Px) for detection. Results were as follows:1 day and 3 days after operation, the model group and the control group had severe liver function damage, with obvious oxidative stress. The CM and ADSCs treatment groups significantly promoted the recovery of liver function, and the expression of oxidative stress related indicators decreased significantly compared with the model group and the control group. After 7 days, each group basically recovered to the preoperative level. The results showed that laparoscopic liver ischemia-reperfusion combined with partial hepatectomy injury can cause oxidative stress in miniature pigs. Adipose-derived mesenchymal stem cells and their condition medium can improve oxidative stress after liver injury.
