Conventional in vitro assays are based on cells grown on two-dimensional (2D) substrates, which are not representative of a true in vivo cell environment. Three-dimensional (3D) cell culture methods, in contrast, allow cells to grow in structures resembling more the in vivo environment. Cells can develop cell-cell and cell-extracellular matrix (ECM) interactions in 3D.
While 3D cultures more accurately approach the in vivo environment, it might be difficult to analyze cells in 3D. However, this is not always the case. This poster explains how to measure cell viability easily in 3D cell cultures using the ViaLight™ Plus BioAssay. Cell viability was determined in two different 3D cell culture systems – the RAFT™ 3D Cell Culture System and classical spheroid cultures generated in ultra-low attachment plates.
Primary Human Hepatocyte (PHH) culture provides the closest in vitro model to human liver that can produce a metabolic profile of a given drug very similar to that found in vivo. Recently we have developed an easy-to-assemble user-friendly in vitro Primary Human Hepatocyte (PHH) 3D-spheroid modelREAD MORE
