This product is a cutting-edge, well-defined serum-free medium specifically designed to induce and expand embryonic-like stem cells (ELSCs) derived from umbilical cord blood. By precisely mimicking the unique microenvironment of early embryonic development and dynamically regulating key signaling pathways for pluripotency maintenance and self-renewal, it efficiently supports the reprogramming of cord blood cells into an embryonic-like state with high pluripotency. This product not only ensures stable karyotypes and multidirectional differentiation potential during long-term culture but also eliminates biosafety risks in clinical applications through its completely xenogeneic-free formulation.
