Hepatocytes were isolated from wild-type, 6–12 week-old C57BL/6 mice (Jackson Laboratory, Bar Harbor, ME). In some experiments, hepatocytes were isolated from Hnf4afl/fl:Alb Cre+ mice that lacked HNF4α expression in adult hepatocytes and Hnf4afl/fl:Alb Cre wild-type littermates (kind gift from Dr. Frank J. Gonzalez) (17 (link)). All mice were cared for in accordance to the National Institutes of Health “Guide for the Care and Use of Laboratory Animals.” Hepatocyte isolation was performed by two-step perfusion using Liver Perfusion and Liver Digest Media (Life Technologies, Pleasanton, CA) followed by separation with 50% Percoll (GE Healthcare Life Sciences, Pittsburgh, PA) density gradient. Purity of live hepatocytes was routinely ≥90% by trypan blue exclusion. Hepatocytes were cultured in 5% fetal calf serum (Hyclone, Logan, UT) in DMEM supplemented with L-glutamine, antibiotics, insulin-transferrin-selenium, and HEPES (Mediatech, Manassas, VA). Inhibitors used and their final concentrations in cell culture were: 50μM Y-27632, 25μM FAK inhibitor-14, 0.5μM blebbistatin, or 20μM U-0126 (Santa Cruz Biotech, Dallas, TX).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
