Dynamic visualization of the recovery of mouse hepatobiliary metabolism to acetaminophen-overdose damage.

Acetaminophen (APAP) overdose is one of the world's leading causes of drug-induced hepatotoxicity. Although traditional methods such as histological imaging and biochemical assays have been successfully applied to evaluate the extent of APAP-induced liver damage, detailed effect of how APAP overdose affect the recovery of hepatobiliary metabolism and is not completely understood. In this work, we used intravital multiphoton microscopy to image and quantify hepatobiliary metabolism of the probe 6-carboxyfluorescein diacetate in APAP-overdose mice.
