Abstract
Cellular reprogramming, whereby cell fate can be changed by the expression of a few defined factors, is a remarkable process that harnesses the innate ability of a cell's own genome to rework its expressional networks and function. Since cell lineages are defined by global regulation of gene expression, transcriptional regulators, and coupled to the epigenetic markings of the chromatin, changing the cell fate necessitates broad changes to these central cellular features. To properly characterize these changes, and the mechanisms that drive them, computational and genomic approaches are perfectly suited to provide a holistic picture of the reprogramming mechanisms. In particular, the use of bioinformatic analysis has been a major driver in the study of cellular reprogramming, both as it relates to induced pluripotency or direct lineage conversion. This review will summarize many of the bioinformatic studies that have advanced our knowledge of reprogramming and address future directions for these investigations.
