Integration-free HiPSC.Our HiPSC are generated with the RNA-based Sendai virus to deliver reprogramming factors to donor skin fibroblasts. Since the virus does not go through a DNA phase, its genetic material and transgenes do not integrate into the host cell genome. HiPSC are validated for viability, karyotype, pluripotency, plating efficiency, morphology, passage number and lack of contamination.

HiPSC-derived Neural Stem Cells (L) and Neurons (R). i-HNSC stained w/ Nestin (neural stem cell marker, green), SOX 2 (stem cell marker, red) & DAPI (nuclear stain, blue). SOX2 & DAPI nuclear co-localization yields purple (Left). Video: Human iPSC-Derived Neurons establish mature, synchronized neuronal network. In real time, Multi-electrode array (MEA) shows optimal electrophysiological activity, which can be modulated by neurotransmitters or small compounds (Right).

Reprogrammingtriggers a cascade of evident changes in the host cells that are recognizable morphologically and through a combination of markers and pluripotency assays. Our HiPSCs display classic pluripotent stem cell morphology, with a high nucleus to cytoplasm size ratio, as well as they are amenable to be cultivated in serum-free media, independent of feeder cells and of feeder-conditioned media as colonies or high density monolayers. hiPSCs are also evaluated for the presence of karyotypic abnormalities. Confirmation of pluripotency is performed through the analysis of expression of several established independent pluripotency markers. Unguided differentiation confirms HiPSC ability to generate cell derivatives of tissues arising from the three embryonic layers.

Cell Characterization. Post-thawing viability of HiPSCs is typically higher than 70%, and HiPSC have demonstrated coherent pluripotent behavior over more than 60 passages. Although it is in theory possible to propagate HiPSCs indefinitely, HiPSC subculturing over passages higher than is usually not recommended, as the chances of karyotypic abnormalities increase. HiPSCs are also tested to ensure absence of microorganism contaminants.
