Immunogenicity and Immunomodulatory Properties of Hepatocyte-like Cells Derived from Human Amniotic Epithelial Cells

Abstract

Hepatocyte transplantation is being trialled as an alternative to whole organ transplant for patients with acute liver failure and liver specific metabolic diseases. Due to the scarcity of human hepatocytes, hepatocyte-like cells (HLC) generated from stem cells may become a viable alternative to hepatocyte transplantation. Human amniotic epithelial cells (hAEC) from the placenta have stem cell-like properties and can be differentiated into HLC. Naïve hAEC have low immunogenicity and exert immunomodulatory effects that may facilitate allogeneic transplantation. However, whether the immunogenicity and immunomodulatory properties alter with differentiation into HLC are unknown. We further chara..
