Electronic Thesis and Dissertation Repository
Mouse embryonic stem cells (mESCs) and mouse epiblast stem cells (mEpiSCs) represent opposite ends of a pluripotency continuum, respectively referred to as naïve and primed pluripotent states. A third, recently discovered intermediate state has been described as the ‘formative state’. Metabolism has been traditionally regarded as a by-product of cell fate; however, recent evidence now supports metabolism as promoting stem cell fate. Pyruvate kinase muscle isoforms 1 and 2 (PKM1 and PKM2) catalyze the final, rate limiting step of glycolysis generating adenosine triphosphate (ATP) and pyruvate; however, the precise role(s) of these isozymes in naïve, formative, and primed pluripotency is …
