Hepatocytes were isolated from male LRep1−/− and LRep1+/+ mice at an age of 6 weeks as described previously55 (link). Cells were plated on collagen A (200 µg/ml in PBS; Biochrom, Berlin, Germany) coated cell culture dishes with Williams E medium (PAN Biotech, Aidenbach, Germany) containing L-glutamine, 10% (v/v) FCS (for the first 4 hours, subsequently FCS free) and 100 nM dexamethasone (Sigma Aldrich) and incubated in a 5% CO2 humidified atmosphere at 37 °C.
The human hepatocellular carcinoma cell line HepG2 was cultured in Dulbecco’s modified Eagle’s medium (DMEM, high glucose) supplemented with 10% (v/v) FCS at 37 °C in 5% CO2.
