Multiphoton dynamic imaging of the effect of chronic hepatic diseases on hepatobiliary metabolism in vivo

We used intravital multiphoton microscopy to study the recovery of hepatobiliary metabolism following carbon tetrachloride (CCl4) induced hepatotoxicity in mouse. Our images were processed by a first order kinetic model to generate rate constant resolved images of the mouse liver. At Day 14 following induction, a restoration of the mouse hepatobiliary function was found. Our approach allows the study of the response of hepatic functions to chemical agents in real time and is useful for studying pharmacokinetics of drug molecules through optical microscopic imaging.
