Epithelial cadherin regulates transition between the naïve and primed pluripotent states in mouse embryonic stem cells

Inhibition of E-cad in mouse embryonic stem cells (mESCs) leads to a switch from LIF-BMP to Activin/Nodal-dependent pluripotency, consistent with transition from a naïve to primed pluripotent phenotype. We have used both genetic ablation and steric inhibition of E-cad function in mESCs to assess alterations to phenotype using quantitative mass spectrometry analysis, network models, and functional assays. Proteomic analyses revealed that one...
