Experimental Protocol


HepG2 cells were cultivated for five days under 2D and 3D statical and perfused conditions. Cultivation was started with 0.25x10^6 cells in 2D and with 1x10^6 vital cells for the 3D experiments. The day of seeding was defined as d0. The groups were classified as follows: 2D, i.e., monolayer cultures, 3D, i.e., statical 3D cultures and BR, which denotes perfused 3D culture of HepG2 cells. The perfusable bioreactor system was operated using a peristaltic pump. It houses the MatriGrid, a polycarbonate-based microporous cellular support. For 3D static cultivation, cell-inoculated MatriGrids were placed in wells of a 24-well plate. Microarray experiments of three 2D (i.e., control), three 3D statically and three actively perfused 3D cultivations were performed at SIRS-Lab GmbH (SIRS-Lab GmbH, Jena, Germany) according to the manufacturer's instructions (Illumina, San Diego, CA). Altogether, 9 RNA samples of hepatocyte cultures and an internal control RNA were hybridized on two HumanHT-12 v4 Expression BeadChips.
