A Molecular Roadmap of Reprogramming Somatic Cells into iPS Cells
Factor-induced reprogramming of somatic cells into induced pluripotent stem cells (iPSCs) is inefficient, complicating mechanistic studies. Here, we examined defined intermediate cell populations poised to becoming iPSCs by genome-wide analyses. We show that induced pluripotency elicits two transcriptional waves, which are driven by c-Myc/Klf4 (first wave) and Oct4/Sox2/Klf4 (second wave). Cell...
متن کاملTime-resolved gene expression profiling during reprogramming of C/EBPα-pulsed B cells into iPS cells
The reprogramming of somatic cells to induced pluripotent stem cells (iPSCs) is lengthy and inefficient. The development of a reprogramming system that allows rapid and synchronous reprogramming to pluripotency is imperative for understanding the mechanism of iPSC formation and for future therapeutic applications. We have recently reported that a short expression in mouse primary B cells of the...
متن کاملGlobal epigenetic changes during somatic cell reprogramming to iPS cells.
Embryonic stem cells (ESCs) exhibit unique chromatin features, including a permissive transcriptional program and an open, decondensed chromatin state. Induced pluripotent stem cells (iPSCs), which are very similar to ESCs, hold great promise for therapy and basic research. However, the mechanisms by which reprogramming occurs and the chromatin organization that underlies the reprogramming proc...
متن کاملReprogramming somatic cells into iPS cells activates LINE-1 retroelement mobility.
Long interspersed element-1 (LINE-1 or L1) retrotransposons account for nearly 17% of human genomic DNA and represent a major evolutionary force that has reshaped the structure and function of the human genome. However, questions remain concerning both the frequency and the developmental timing of L1 retrotransposition in vivo and whether the mobility of these retroelements commonly results in ...
متن کاملGeneration of Induced Pluripotent Stem (iPS) Cells by Nuclear Reprogramming
During embryonic development pluripotency is progressively lost irreversibly by cell division, differentiation, migration and organ formation. Terminally differentiated cells do not generate other kinds of cells. Pluripotent stem cells are a great source of varying cell types that are used for tissue regeneration or repair of damaged tissue. The pluripotent stem cells can be derived from inner ...
