This product is a serum-free medium with fully disclosed ingredients, serving as an optimized version of classic media such as mTeSR. Its formulation is extremely streamlined, containing only eight essential components. Not only does it efficiently support high-quality expansion and long-term maintenance of undifferentiated states in human pluripotent stem cells, but by eliminating redundant components, it significantly enhances the stability, consistency, and safety of the culture system, greatly reducing experimental variables and differentiation risks.
