Abstract

Living organisms, from virus to human, rely on the transcription machinery to express specific parts of their genomes to execute critical biological functions during their life cycle by responding to environmental or developmental signals. Thus, transcription constitutes a critical step in regulating biological processes, and transcription factors have been considered as master switches for cell fate determination. Stem cell biology has benefited from rapid advances in recent years, largely because of the characterization of several transcription factors as master regulators of stem cell pluripotency. The same factors, viz. Oct4, Sox2, Nanog, Klf4, and Myc, have been shown to possess the magic power to reprogram somatic cells into pluripotent ones, a remarkable achievement with both practical and theoretical implications. This minireview summarizes recent advances in pluripotency and reprogramming by focusing on key transcription factors and the likely mechanisms.

Summary

Regulation of Pluripotency and Reprogramming by Transcription Factors*

The same factors, viz. Oct, Sox, Nanog, Klf, and Myc, have been shown to possess the magic power to reprogram somatic cells into pluripotent ones, a remarkable achievement with both practical and theoretical implications This minireview summarizes recent advances in pluripotency and reprogramming by focusing on key transcription factors and the likely mechanisms. Recent advances in understanding the molecular mechanisms governing ES cell pluripotency have provided insights into the role of transcription factors such as Oct and Nanog in maintaining ES cells in the undifferentiated state (8 –11) These pluripotency factors, Oct, Sox, and Nanog, have been shown to participate in the reprogramming of differentiated cells back to pluripotent states [12, 13]. I will attempt to explain pluripotency and reprogramming in the context of transcription factors and will discuss the related challenges and opportunities
