Quantification of Efflux Transporter Activity in 3D Human Liver Microtissues
8 Sept 2015A functional impairment of hepatobiliary transporters such as bile salt export pump (BSEP) and multidrug resistance-associated protein 2 (MRP2) are strongly associated with an increased risk of liver injury. The use of 3D human liver microtissues for assessing hepatobiliary transporter function is presented in this poster. Confocal imaging was used to assess BSEP-mediated efflux of cholyl-lysyl-fluorescein (CLF) and MRP2-mediated efflux of 5-chloromethylfluorescein diacetate (CMFDA) into the bile canaliculi. 3D InSight Human Liver Microtissues were produced with InSphero’s propietary production process and maintained in GravityTRAP plates until further analysis.

Cell / Tissue CultureCell culture or tissue culture is used to study the biology of cells or tissues and to isolate cellular products in an environment which can be manipulated and well defined. Accurately control your culture environment with bioreactors or culture incubators, bind your cells to a surface or together with an extracellular matrix. Distinguish cell types with differential media or proliferate cells with certain characteristics using selective media. Enrich your media with supplements such as growth factors, sera and vitamins.
