Bivalent Metabolism Maintains hESC Pluripotency

Nicotinamide adenine dinucleotide (NAD+) induces an intermediate state of naivety in human embryonic stem cells (hESCs) characterized by a shift from glycolytic to oxidative metabolism, increased self‐renewal, and epigenetic alterations. Conversely, inhibition of the malate aspartate shuttle (MAS), which recycles NAD+, causes a dramatic loss of oxidative metabolism and pluripotency marker expression.

Oct4 Plays Detrimental Role in Mouse Induced Pluripotent Stem Cell Generation

The generation of induced pluripotent stem cell employing the lentiviral transduction of Sox2, Klf4, and Myc only generates cells with improved developmental potential
