This product is a chemically defined medium meticulously designed to efficiently generate neuroblasts from human embryonic stem cells and further induce their differentiation into the neural lineage. By precisely regulating key neurodevelopmental signaling pathways such as Sonic Hedgehog, Wnt, and BMP, it effectively promotes the formation of structurally organized, highly uniform neurospheres from hESCs and stably guides their differentiation into specific neural cell types including neurons, astrocytes, and oligodendrocytes.
