Figure 1. Schematic of Reversion of Primed to Naïve hPSCs
Primed hPSCs, grown either in mTeSR™1 or TeSR™-E8™ on Corning® Matrigel®, are plated as single cells on inactivated murine embryonic fibroblasts (iMEFs) and treated with Rho-kinase inhibition (10 μM Y-27632) for 24 hours in hypoxic conditions. On day 1, medium is changed to Induction Medium 1 supplemented with a histone deacetylase inhibitor (HDACi) and cells are cultured for 3 days with daily medium changes. On day 4, medium is changed to Induction Medium 2 and cells are cultured until day 11 with daily medium changes. On day 11, hPSCs are passaged as single cells onto fresh iMEFs and subsequently passaged every 3 - 4 days until the end of passage 2 in Induction Medium 2. From passage 3, hPSCs are cultured in Induction Medium 3. Background differentiation will decrease between passage 3 and 8. At this time cells can be transferred into NaïveCult™ Expansion Medium for long-term maintenance and expansion.
Figure 2. Human ES and iPS Cells Can Be Reverted to a Naïve State
Representative images of human (A) passage-7 H9 ES cells and (B) passage-9 WLS-1C iPS cells that were reverted to a naïve state using the NaïveCult™ Induction Kit and subsequently cultured in NaïveCult™ Expansion Medium. During reversion, colonies change from a flat morphology to a tightly packed, domed morphology with refractive edges characteristic of naïve-state hPSCs.

Gene expression profile of human (A) H9 ES cells and (B) WLS-1C iPS cells reverted using the NaïveCult™ Induction Kit and maintained in NaïveCult™ Expansion Medium.
Figure 4. Reset Naïve Human PSCs Cultured in NaïveCult™ Expansion Medium are Capable of Tri-Lineage Differentiation Following Re-Priming
Reset naïve human iPS cells cultured in NaïveCult™ Expansion Medium were re-primed in mTeSR™1 and differentiated to all three somatic lineages. (A) Representative flow cytometry plot of human WLS-1C iPS cells differentiated using the STEMdiff™ Definitive Endoderm Kit (Catalog #05110) demonstrating >90% CXCR4+/SOX17+ definitive endodermal progenitors. (B) Representative flow cytometry plot of human WLS-1C iPS cells differentiated using STEMdiff™ Mesodermal Induction Medium (Catalog #05220) demonstrating >80% Brachyury+/OCT4- mesodermal progenitors. (C) Representative immunofluorescence image of PAX6 (green) and SOX1 (red) double positive neural progenitors derived from human WLS-1C iPS cells differentiated using the STEMdiff™ SMADi Neural Induction Kit (Catalog #08581).
