Application Note: 3D Cell Culture: A Review of Current Techniques
22 February 2016

Over the last decade, a central focus of drug discovery efforts has been the incorporation of in vitro testing models that better mimic in vivo conditions found within the target patient. An initial step saw a move away from biochemical assays using purified drug target, in favor of a cell-based approach which utilized over-expression of drug target in common host cell lines, such as CHO and HEK-293. The quest for greater physiological relevance proceeded to the use of primary cells, preferably human if supply was adequate, and the reliance on endogenous expression of drug target should detection technology be sensitive enough. This white paper provides an overview of current techniques for optimum 3D cell culture.
