Abstract

Regenerative medicine is a highly advanced medical field that aims to restore tissues and organs lost due to diseases and injury using a person's own cells or those of others. Direct cellular reprogramming is a promising technology that can directly induce cell-fate conversion from terminally differentiated cells to other cell types and is expected to play a pivotal role in applications in regenerative medicine. The induction of direct cellular reprogramming requires one or more master transcription factors with the potential to reconstitute cell type-specific transcription factor networks. The set of master transcription factors may contain unique transcription factors called pioneer factors that can open compacted chromatin structures and drive the transcriptional activation of target genes. Therefore, pioneer factors may play a central role in direct cellular reprogramming. However, our understanding of the molecular mechanisms by which pioneer factors induce cell-fate conversion is still limited. This review briefly summarizes the outcomes of recent findings and discusses future perspectives, focusing on the role of pioneer factors in direct cellular reprogramming.
