Abstract:
Vitamin C has recently received attention because of its ability to improve induced pluripotent stem cells (iPSCs) generation [1-3] and maintain a blastocyst-like state in ES cells [4]. However, the underlying mechanisms are not fully understood. In this study, we found that vitamin C maintained the morphology of mouse embryonic stem cell (mESC) colonies and inhibited mESC differentiation. Gene expression profiling revealed that the genes down-regulated by vitamin C were grouped in the regulation of differentiation and development, while most of the up-regulated genes were enriched in the regulation of transcription involving numerous pluripotency factors, which was further confirmed by real time quantitative PCR. For the key pluripotency factor Nanog, vitamin C increased its promoter activity and protein level. In addition, pathway screening indicated that vitamin C may affect various signaling pathways. Our study provides new insights into vitamin C-mediated pluripotency maintenance of mESCs.

Compact chromatin makes reprogramming difficult. Enzymes, such as histone demethylases and acetyltransferases, are often added during reprogramming to loosen the chromatin, making the DNA more accessible to transcription factors. Molecules that inhibit histone...
