This product is a specialized medium designed to maintain the in vitro growth and pluripotent state of human malignant multiple teratoma NTERA2 cell lines. Its formulation precisely mimics the microenvironment essential for human embryonal carcinoma cell survival. By meticulously regulating key signaling pathways, it ensures NTERA2 cells consistently maintain their characteristic undifferentiated clonal morphology, sustained self-renewal capacity, and high expression of pluripotency markers such as OCT-4 and SSEA-3.
