iSTEM是一款卓越的小鼠胚胎干细胞维持培养基。该款产品包含三种小分子抑制物，从而阻断干细胞分化的信号通路，同时维持细胞的多能干性（pluripotency）。 iSTEM可以被应用于难以获得ES细胞的小鼠品系，获取到ES细胞系(1)。

iSTEM培养基中的小鼠ES细胞与在添加了Leukemia Inhibitory Factor (LIF) 和 serum/Bone Morphogenetic Protein (BMP)的培养基的细胞相比，增殖速度加倍(1)。另外，在iSTEM中培养的小鼠ES细胞产生细胞聚落（clone）的能力显著提高（enhanced clonogenicity）,从而可以在单细胞铺板后（single cell deposition），产生更多的干细胞克隆。

iSTEM is a compley defined cell culture medium for deriving, maintaining, and propagating mouse embryonic stem (ES) cells. This media formulation captures mouse ES cells in their basal state by blocking the inductive pathways of differentiation with selective small molecule inhibitors. The medium contains three small molecule inhibitors that block differentiation-inducing signals and promote cell survival, enabling maintenance of pluripotency without the need for additional stimulatory cytokines. iSTEM medium can also be used to derive mouse ES lines from strains that have proven refractory to ES cell derivation under standard conditions (1).

Mouse ES cells cultured in iSTEM medium continually expand at a doubling rate that is comparable to that of cells cultured in the presence of Leukemia Inhibitory Factor (LIF) and serum/Bone Morphogenetic Protein (BMP) (1). In addition, culture in iSTEM medium enhances clonogenicity; a higher frequency of pluripotent colonies are established after single cell deposition.
