TL;DR
Injecting stem cells directly into the liver is more effective at helping it recover from injury and surgery than injecting a protective substance into the bloodstream.
Key Finding
Both hydrogen-rich saline and adipose-derived stem cells reduced liver damage and promoted recovery after surgery in pigs, but stem cell injection into liver tissue was more effective than hydrogen-rich saline injection into a vein.
Summary
This study compared two treatments for protecting the liver after surgery in pigs: hydrogen-rich saline (salt water containing dissolved hydrogen) injected into a vein, and stem cells (immature cells that can develop into specialized cells) injected directly into liver tissue. Both treatments reduced liver damage and helped the liver recover better than no treatment, but the stem cell injection worked better than the hydrogen-rich saline at promoting liver function recovery.
Practical Takeaway
This is an animal study in pigs, so results cannot be directly applied to humans. While the findings suggest hydrogen-rich saline may have protective effects on liver tissue, much more research—including human studies—would be needed to determine if this applies to people. The study does not provide evidence that hydrogen water would have similar effects.
Abstract
Aim: To compare and evaluate the hepatoprotective effect of liver parenchyma injection of ADSCs and portal vein injection of HRS in laparoscopic hepatic ischemia reperfusion combined with hepatectomy injury in miniature pigs. Methods: Eighteen miniature pigs were randomly assigned to IRI group, HRS group and ADSCs group. HRS was injected through the portal vein 10 min before reperfusion, 1 d, 2 d, and 3 d after surgery. ADSCs were injected into liver parenchyma after hepatectomy. The serum and liver tissue samples were collected at different time points (preoperative, and postoperative at 1 d, 3 d and 7 d). Results: Compared with the IRI group, both ADSCs and HRS groups can promote liver function recovery, reduce oxidative stress, reduce inflammation, and promote liver regeneration. Compared with HRS, ALT and TBIL in ADSCs group were significantly decreased at 3 d, and AST was significantly reduced at 1 d. The activities of SOD and GSH-Px in ADSCs group were significantly higher than that in HRS group, but the MDA level in HRS group was markedly lower than that in ADSCs group at 1 d. IL-1β was significantly lower in the ADSCs group than in the HRS group at 1 day after operation. The expressions of HGF and PCNA were significantly higher than that in the HRS group at 3 day after surgery. Conclusion: Our study has demonstrated that HRS and ADSCs have significant hepatoprotective effects in miniature pigs after HIRI and hepatectomy injury. However, liver parenchyma injection of ADSCs is more beneficial to the recovery of liver function than portal vein injection of HRS.
