When used together, Essential 6™ Medium and Essential 8™ Medium streamline the generation, expansion, and differentiation of pluripotent stem cells (PSCs) by offering a feeder-free, xeno-free system for all three steps.

Originally developed and published by Guokai Chen et al.1 in the laboratory of James Thomson, Essential 8™ Medium contains only the essential components needed for stem cell culture*. Essential 6™ Medium uses the same base formulation as Essential 8™ Medium, but without TGFβ or bFGF to allow for reprogramming and differentiation.
