This product is a specialized medium designed to induce and regulate the directed differentiation of embryonic carcinoma (EC) cells. By precisely regulating key signaling pathways and providing specific induction factors and differentiation-stimulating components, it efficiently initiates and sustains the differentiation process of EC cells from a pluripotent state into specific germ layer lineages (such as ectoderm, mesoderm, or endoderm). It also stably supports the functional maturation and specific marker expression of differentiated cells.
