Mouse embryonic stem (mES) cells are pluripotent cells derived from the inner cell mass of pre-implantation blastocysts. Mouse induced pluripotent (miPS) cells are pluripotent cells generated by reprogramming mouse somatic cells using four transcription factors, Oct-4, Klf-4, Sox-2, and c-Myc, or their variants. Both mESC and miPSC can self-renew and have the ability to generate all three germ layers: ectoderm, mesoderm, and endoderm. In vitro, mESC/iPSC are normally maintained and propagated on mouse fibroblast feeders or in feeder-free conditions in media containing LIF/ESGRO. However, spontaneous differentiation may occur in subpopulations of cells. Several pluripotent markers are commonly used to distinguish pluripotent mESC/iPSC from differentiated cells.

EMD Millipore’s Fluorescent Mouse ES/iPS Cell Characterization Kit contains a range of sensitive tools for the phenotypic assessment of the pluripotent status of mouse ES/iPS cells. Included in the kit is an enzymatic assay to measure alkaline phosphatase activity in the cells along with validated directly conjugated antibodies to pluripotent transcription factors, Oct-4, Sox-2 and DPPA-2 and cell surface epitope SSEA-1 to enable rapid immunocytochemical marker analysis. The Dapi nuclear dye is conveniently included to aid in cell quantification. While the expression levels of pluripotent markers are expected to be diminished upon differentiation, each possess specific expression kinetics.
