Bioinformatics Studies on Induced Pluripotent Stem Cell
The induced pluripotent stem cells (iPSCs), generated from transcription factor-induced reprogramming, hold
the great promise as the next generation materials for regenerative medicine. Intensive follow-up studies have
accumulated a large amount of high-throughput data in transcription, proteomics, methylation, and other levels, which
makes the computational studies feasible. Here we briefly review the recent bioinformatics efforts to study iPSCs.
Specifically, we will summarize several comparison studies to determine how closely human iPSCs resemble human
embryonic stem cells (ESCs) from sequence, gene expression profile, chromatin structure, DNA methylation, proteomics,
and function aspects. Then computational methods to assess iPSC’s pluripotency in a cost-effective yet accurate way are
introduced. Finally, we will indicate the further biomolecular network studies to understand the underlying mechanism for
cell reprogramming and the dynamics within this biological process.
