Cell-of-origin specific 3D genome structure acquired during somatic cell reprogramming [Expression]

ABSTRACT: We studied genome topology dynamics during reprogramming of different somatic cell types with highly distinct genome conformations. We find large-scale TAD repositioning and alterations of tissue-restricted genomic neighborhoods and chromatin loops, effectively erasing the somatic cell specific genome structures while establishing an embryonic stem cell-like 3D genome. Yet, early passage iPSCs carry topological hallmarks that enable discerning their cell-of-origin. These hallmarks are not remnants of somatic chromosome topologies. Instead, the distinguishing topological features are acquired during reprogramming, as we also find for cell-of-origin dependent gene expression patterns.

In addition, expression analysis was performed in E14 embryonic stem cells

Local Genome Topology Can Exhibit an Incompletely Rewired 3D-Folding State During Somatic Cell Reprogramming

Project description:The pluripotent genome is folded in a hierarchy of sophisticated topologies that markedly reconfigure during cell fate transitions. A critical unknown is whether chromatin folding is reversible and functionally linked to the re-establishment of pluripotency in somatic cell reprogramming. Here we integrate classic epigenetic marks with high-resolution architecture maps in embryonic stem (ES) cells, ES-derived neural progenitor cells (NPCs) and NPC-derived induced pluripotent stem (iPS) cells. Collectively we demonstrate that chromatin architecture is only partially reconfigured during somatic cell reprogramming and that pluripotent elements can retain architectural memory from their somatic cell of origin.

Identification of Xenopus laevis egg extract fraction stimulating somatic DNA replication through LC-MSMS

Project description:In several metazoans the number of active replication origins in embryonic nuclei is higher than in somatic ones, ensuring rapid genome duplication during synchronous embryonic cell divisions. High replication origin density can be restored by somatic nuclear reprogramming. However, mechanisms underlying high replication origin density formation coupled to rapid cell cycles are poorly understood. Here, we characterized a fraction of Xenopus egg extract able to stimulate somatic DNA replication.

Expression data of human somatic cell types and induced pluripotent stem cells

Project description:Transcription factor-mediated reprogramming yields induced pluripotent stem cells (iPSC) by erasing tissue specific methylation and re-setting DNA methylation status to an embryonic stage. We compared bona fide human iPSC derived from umbilical cord blood (CB) and neonatal keratinocytes (K). Through both incomplete erasure of tissue specific methylation and de novo tissue specific methylation, CB-iPSC and K-iPSC are distinct in genome-wide DNA methylation profiles. Functionally, CB-iPSC displayed better blood formation in vitro, whereas K-iPSC differentiated better to a keratinocyte fate, implying that the tissue of origin needs to be considered in future therapeutic applications of human iPSCs. We performed gene expression and global DNA methylation profiling on iPS and the source somatic cell types to search for evidence of epigenetic memory. We performed gene expression profiling to identify genes differentially expressed between keratinocytes and cord blood, and from induced pluripotent stem cells from these somatic tissues.
