Does mesenchymal stem cell improve the liver regeneration after the 70% hepatectomy?

Purpose:: To evaluate the effects of mesenchymal stem cells on liver regeneration in rats following a 70% hepatectomy.

Methods:: Forty rats were subjected to 70% hepatectomy and then ~106 mesenchymal stem cells (test group), or saline solution (control group), were infused into their livers via the portal vein. Each treatment group was divided into early and late subgroups (euthanized 3 d and 5 d following the operation, respectively).
