Project description:Inducing pluripotency from mouse somatic cells by small-molecule compounds [Phalanx Mouse OneArray]
| PRJNA209586 | ENA
Project description:Pluripotent stem cells can be induced from somatic cells, providing an unlimited cell resource for regenerative medicine. However, genetic manipulation and difficult-to-manufacture strategies used in reprogramming limit their clinical applications. Here, we show pluripotency can be induced from mouse somatic cells by specific small-molecule compounds. The completely chemically-induced pluripotent stem cells (CiPSCs) can be stably maintained in embryonic stem cell (ESC) culture medium and resemble ESCs in terms of their gene expression profiles, epigenetic status, and potential for differentiation and germline transmission. These findings suggest that exogenous master genes are dispensable for cell fate reprogramming and pave the way for the clinical application of somatic reprogramming techniques. Chemicals' acronym: V, VPA; C, CHIR; 6, 616452; T, tranylcypromine; F, FSK; Z, DZNep; P, PGE2; R, RG108; S, SRT1720; M, 2-Me-5HT; D, D4476; B, Sodium butyrate. mRNA expression analysis of mouse embryonic fibroblasts (MEFs), GFP- cells, GFP+ clusters,GFP+ colonies, embryonic stem cells (ESCs) and CiPSCs by RNA sequencing.

To compare the global gene expression pofile of mouse embryonic fibroblasts (MEFs), mouse adult lung fibroblasts (MAFs), mouse neonatal fibroblasts (MNFs), adipose-derived stem cells (ADSCs), chemical induced pluripotent stem cells (CiPS), embryonic stem cells (ESCs) and OSKM-iPSCs. We profiled the mRNA expression of each sample by microarray (Mouse OneArray® v2, Phalanx). Different sample set was normalized for different purpose. Set1: MEFs1, CiPS34, MNF CIPS7, CiPS50 CiPS21, OSKM-iPS1 and ESCs1 were analyzed, each sample have three replicates; Set2: MNFs, MAFs, ADSCs, MNF CiPS1, MAF CiPS3, CiPS45, ADSC CiPS2, OSKM iPS2 and ESCs2 were analyzed, each sample have three replicates; Set3: WT MEFs, ESCs3, CiPS WT1 and CiPS WT2 were analyzed, each sample have two replicates; Set4: MEFs2, SKM-FSK1, SKM-FSK2 and ESCs4 were analyzed, each sample have three replicates; Set5: MEFs3, ESCs5, CiPSCs, D12, D20 and D32 were analyzed, each sample have two replicates.

Project description:Recent reports have proposed a new paradigm for obtaining mature somatic cell types from fibroblasts without going through a pluripotent state, by briefly expressing canonical iPSC reprogramming factors Oct4, Sox2, Klf4 and c-Myc (abbreviated as OSKM), in cells expanded in lineage differentiation promoting conditions. Here we apply genetic lineage tracing for endogenous Nanog, Oct4 and X chromosome reactivation during OSKM induced trans-differentiation, as these molecular events mark final stages for acquisition of induced pluripotency. Remarkably, the vast majority of reprogrammed cardiomyocytes or neural stem cells derived from mouse fibroblasts via OSKM mediated trans-differentiation were attained after transient acquisition of pluripotency, and followed by rapid differentiation. Our findings underscore a molecular and functional coupling between inducing pluripotency and obtaining “trans-differentiated” somatic cells via OSKM induction, and have implications on defining molecular trajectories assumed during different cell reprogramming methods. poly RNA-Seq and Chromatin accesibility (ATAC-seq) were measured during conversion of mouse embryonic fibroblasts to neural stem cells using OSKM trans-differentiation method, as well as in mouse emrbyonic fibroblasts, iPSCs and mouse ESCs.
