Intravital imaging of hepatobiliary excretion is vital for elucidating liver metabolism. In this work, we describe a novel method to observe the intravital dynamics of the uptake, processing, and excretion of an organic anion, 6-carboxyfluorescein diacetate (6-CFDA) in the hepatobiliary system. This is achieved by the use of multiphoton microscopy and an intravital hepatic imaging chamber. The high-quality images show sequential uptake and processing of 6-CFDA from the hepatocytes and the subsequent excretion into bile canaliculi within approximately 50 min. This is a promising technique to study intravital hepatic physiology and metabolism.
