Rigenerazione epatica mediante l'impiego di cellule staminali mesenchimali in un modello murino di danno epatico tetracloruro-indotto

Bone marrow-derived mesenchymal stem cells (MSCs) have been investigated as marker of liver regeneration in an experimental model of acute liver failure (ALF). This model was created in Wistar rats through an intraperitoneal injection of carbon tetrachloride (CCl4). MSCs (3 million) were collected by long bones of 10 Wistar rats and then intravenously infused 24 hours after induction of ALF in 16 rats, Group A. In control Group B, 16 rats received a peritoneal injection of CCl4, and an intravenous infusion of normal saline. All rats were sacrificed at 2, 3, 4 and 7 days post-CCl4-injection. To assess the efficacy of the induction of the ALF, 4 rats Group (C) were sacrified 1 day after poisoning. Biochemical markers (BM) of liver function as platelets counts and pathology examination of the procured livers were staged on post-infusion-days 2, 3, 4 and 7. In Group A platelets count was higher than in the untreated control Group on post-CCl4-infusion day 2nd (p = 0.02) and 3rd (p=0.001). Also The trend of BM as transaminases was higher in the non-treated Group B, GOT (p=0.002), GPT (p<0.0001). Pathology examination showed greater grade of hepatocellular necrosis, and neutrophilic infiltration in Group B (p=0.02). MSCs infusion determined a less aggressive picture of hepatic damage.
