From Liver Development to Cell Therapy for Liver Diseases

The Gouon-Evans lab is interested in understanding the liver development and regeneration in mice and human using pluripotent stem cells as a model system and cellular source for liver cell therapy.


Projects currently developed in the lab:


Understanding early hepatic specification of the endoderm in the mouse: crosstalk between endoderm and endothelial cells

Studies in animal models have shown that complex cell-cell interactions are required for hepatic specification and maturation during liver development. Namely, endothelial cells are observed very early around the hepatic endoderm, and in their absence the hepatic endoderm does not expand to form the liver bud. The relevance of the endoderm-endothelial cell interactions is not understood. Using the mouse embryonic stem (ES) cell differentiation system as well as the early mouse embryo, we recently demonstrated that the endothelial cell niche induces hepatic specification through dual repression of Wnt and Notch signaling. Ongoing studies aim at revealing further pathways involved in the endothelial cells – endoderm crosstalk required for hepatic specification.


Directed differentiation of pluripotent stem cells toward functional mouse and human hepatocytes for cell Therapy in liver diseases

The use of ES or induced pluripotent stem (iPS) cell differentiation cultures to generate functional hepatic cells for cell therapy of liver diseases is still an ongoing challenge. Even though a growing literature has established efficient protocols to generate such cells in vitro, the pluripotent stem cell-derived hepatic cells remain inefficient at repopulating diseased livers. Our research is focused on identifying and modulating the molecular pathways required for successful liver regeneration following hepatic cell transplantation into a liver deficient mouse model.

Industry Relationships

Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device and biotechnology companies to improve patient care, develop new therapies and achieve scientific breakthroughs. In order to promote an ethical and transparent environment for conducting research, providing clinical care and teaching, Mount Sinai requires that salaried faculty inform the School of their relationships with such companies.

Dr. Gouon-Evans did not report having any of the following types of financial relationships with industry during 2015 and/or 2016: consulting, scientific advisory board, industry-sponsored lectures, service on Board of Directors, participation on industry-sponsored committees, equity ownership valued at greater than 5% of a publicly traded company or any value in a privately held company. Please note that this information may differ from information posted on corporate sites due to timing or classification differences.

Mount Sinai's faculty policies relating to faculty collaboration with industry are posted on our website. Patients may wish to ask their physician about the activities they perform for companies.
