一般描述
These hiPSC-derived NPCs proliferate as an adherent cell monolayer with greater than 80% expression of the appropriate neural stem cell markers, including Nestin and Sox-2. Cells are provided at passage 3 and can be expanded for a further three to five passages with ENStem-A Neural Expansion Medium (Cat. No. SCM004). Human NPCs can be further differentiated to terminal neurons by the use of the Human ES/iPS Neuronal Differentiation Medium (Cat. No. SCM111) or ENStem-A Neuronal Differentiation Medium (Cat. No. SCM017). Differentiation leads to greater than 80-90% of the cells expressing mostly neuronal markers, bIII-tubulin and MAP2.
Human iPSC-derived NPCs can be used for a variety of research applications including studies of neurotoxicity, co-culture applications and screening for molecules that induce or inhibit preferential differentiation to mature neurons.

Dual SMAD inhibition is a well-established method to derive neural progenitor cells from both human ES and iPS cells. This protocol uses two SMAD inhibitors, Noggin and SB431542, to drive the rapid differentiation of ES/iPS cells into a highly enriched population of NPCs. Noggin acts as a BMP inhibitor and SB431542 inhibits the Lefty/Activin/TGFβ pathways by blocking the phosphorylation of ALK4, ALK5, and ALK7 receptors. In an effort to make a more defined and optimized neuronal differentiation protocol, Li and colleagues modified the original protocol to establish a completely small molecule-based differentiation method, which relies on three small molecules to inhibit GSK-3β (CHIR99021), TGFβ (SB431542), and Notch (compound E) signaling pathways, along with human LIF3. This new small molecule-based neural differentiation protocol increased neural differentiation kinetics and allowed the derivation of truly multipotent neural stem cells that respond to regional patterning cues specifying forebrain, midbrain, and hindbrain neural and glial subtypes.
