The new murine hepatic 3A cell line responds to stress stimuli by activating an efficient Unfolded Protein Response (UPR)

In the present study we have investigated the properties of a novel cell line (3A cells) obtained from the liver of 14.5. days post coitum (dpc) wild-type mouse embryo. 3A cells morphology was characterized by fluorescent localization of F-actin and β-catenin. The expression of specific genes and proteins essential to liver function in these cells was comparable or even more efficient then in the differentiated hepatocytic cell line MMH-D6. 3A cells also showed the capability to excrete molecules in extracellular spaces resembling functional bile canaliculi, glycogen storage activity and the ability to control retinol-binding protein 4 secretion in response to retinol deprivation. Their re…
