Defined animal component-free medium for the differentiation of human ES and iPS cells to definitive endoderm.

STEMdiff™ definitive endoderm kit is a complete, serum- and animal component-free medium and supplement kit that supports highly efficient differentiation of human embryonic stem (ES) cells and induced pluripotent stem (iPS) cells to definitive endoderm cells. Cells differentiated using STEMdiff™ definitive endoderm kit express high levels of endoderm markers, including CD184 (CXCR4), SOX17, FOXA2, and c-KIT, and lack expression of ectoderm, mesoderm, and pluripotency markers. The definitive endoderm cells produced using this kit are multipotent and capable of further differentiation towards cells of the pancreatic, intestinal, pulmonary, and hepatic lineages, thus providing a robust tool for developmental studies, disease modeling, and drug discovery.​ This kit is optimised for differentiation of cells maintained in mTeSR™1. For differentiation of cells maintained in TeSR™-E8™, please see the STEMDiff™ Definitive Endoderm Kit (TeSR™-E8™ optimised).
