General description

The Human STEMCCA Constitutive Polycistronic (OKSM) Lentivirus Kit contains high titer polycistronic (OKSM) lentivirus and Polybrene transfection reagent that have been validated for the generation of human induced pluripotent stem cells from human foreskin fibroblasts (HFFs). The STEMCCA vector is comprised of the transcription factors human Oct-4, Klf4, SOX-2, and c-Myc (OKSM), separated by the self-cleaving 2A peptide and IRES sequences (Sommer CA, 2009). The use of a single polycistronic lentiviral vector significantly improves reprogramming efficiencies and reduces the number of viral integrations.

Analysis Note

Tested to confirm the generation of iPS cells from p6 human foreskin fibroblasts. Other cell types have not been tested and thus similar results can not be guaranteed.

Other Notes

Neural Induction Medium Efficiently Generates Multipotent Neural Progenitors from Human iPS Cells

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.
