Cell based therapy for liver disease

Regenerative medicine has been revolutionized by the induced pluripotent stem (iPS) cell technology and a lot of effort is spent in establishing autologous cell therapies. One of the major hurdles of this seemingly straightforward approach is the lack of suitable small animal models to validate the true nature of stem cell derived hepatocytes. Our laboratory has the opportunity to validate these hepatocytes and explore cell-based therapy in recently developed xenotransplantation model (Bissig et al. PNAS 2007). We are further developing novel genomic approaches to program stem cells into hepatocytes or even normal skin cells into hepatocytes (transdifferentiation).

Recent advancements led to a human liver chimerism of 95% and propagation of hepatitis B and C virus in these humanized mice (Bissig et al. Journal of Clinical Investigation 2010). One of the ongoing projects in our lab is the evaluation of a new class of antiviral drugs against viral hepatitis. This is a multicenter, NIH sponsored collaborative effort.
