Abstract EN
Induced pluripotent stem cells (iPSCs) are generated through a gradual process in which somatic cells undergo a number of stochastic events.
In this study, we examined whether two different doxycycline-inducible iPSCs, slow-forming 4F2A-iPSCs and fast-forming NGFP-iPSCs, have equivalent levels of pluripotency.
Multiplex reverse-transcriptase PCR generated gene expression profiles (GEPs) of 13 pluripotency genes in single initially formed-iPSC (if-iPSC) colonies of NGFP and 4F2A group.
Assessment of GEP difference using a weighted root mean square deviation (wRMSD) indicates that 4F2A if-iPSCs are more closely related to mESCs than NGFP if-iPSCs.
Consistently, Nanog and Sox2 genes were more frequently derepressed in 4F2A if-iPSC group.
We further examined 20 genes that are implicated in reprogramming.
They were, overall, more highly expressed in NGFP if-iPSCs, differing from the pluripotency genes being more expressed in 4F2A if-iPSCs.
wRMSD analysis for these reprogramming-related genes confirmed that the 4F2A if-iPSC colonies were less deviated from mESCs than the NGFP if-iPSC colonies.
Our findings suggest that more important in attaining a better reprogramming is the mode of action by the given reprogramming factors, rather than the total activity of them exerting to the cells, as the thin-but-long-lasting mode of action in 4F2A if-iPSCs is shown to be more effective than its full-but-short-lasting mode in NGFP if-iPSCs.
