Hepatic differentiation of human amniotic epithelial cells and in vivo therapeutic effect on animal model of cirrhosis.

Background And Aim: Human amniotic epithelial cells (hAECs) have been touted as an ideal stem cell candidate, being ethically neutral, immunologically naïve, plentiful in origin, and retaining plasticity in its fetal stage. We hypothesized that by applying natural physiological signals of the developing liver, hAECs can be coaxed into becoming functional immunopermissive hepatocyte-like cells. These cells would have tremendous potential for allogenic cellular transplantation in the treatment of chronic liver insufficiency.
