Provided is a cocktail of factors for converting/reprogramming non-naïve pluripotent stem cells into TGFβ signaling-independent (TSI) naïve induced pluripotent stem cells (iPSCs). Also provided are methods for reprograming a non-naïve PSC into a TSI naïve iPSC by contacting the cell to be reprogrammed with effective amounts of compounds for a sufficient period of time to reprogram the cell into a TSI naïve iPSC.
