Mice With "Humanized" Livers Improve Early Drug Testing, Stanford University School of Medicine Scientists Show

Stanford University School of Medicine scientists have used bioengineered mice with livers composed largely of human cells to characterize a drug about to enter early-stage clinical development for combating hepatitis C. Tests using the new mouse model accurately predicted significant aspects of the drug's behavior in humans — including its interaction with another drug and the profile of its major breakdown products in the body (called metabolites) — far more accurately than would have been achieved using current methods.
