Netrin-1 facilitates somatic cell reprogramming by limiting Dcc pro-apoptotic activity.

Project description:The generation of induced pluripotent stem (iPS) cells holds great promise in regenerative medicine. However, the relative flaws in the understanding of the molecular mechanisms promoting or limiting reprogramming still hinder the efficient generation of high quality iPS cells. Whereas modulation of the initial Oct4, Sox2, Klf4 and c-Myc (OSKM) cocktail with new transcription factors has been extensively documented, comparatively little is known about soluble molecules promoting the process, even if such recombinant factors could be highly valuable for therapeutic applications. In this study we developed a large-scale identification method to uncover novel programmed cell death (PCD)-related mechanisms limiting somatic cell reprogramming to pluripotency (SCRP). We identified Netrin-1 and its dependence receptor Dcc (Deleted in Colorectal Carcinoma), previously described for their respective survival/death functions both in normal and oncogenic contexts, as novel key SCRP modulators. We show that the early phase of SCRP is accompanied with a strong Netrin-1 deficiency, due to the improper epigenetic regulation of the Ntn1 promoter by OSKM. Mechanistically, we demonstrate that such Netrin-1 imbalance induces apoptosis mediated by the dependence receptor Dcc in a p53-independent manner. Correction of the Netrin-1/Dcc equilibrium by gain-of-ligand and loss-of-receptor experiments constrains apoptosis and improves reprogramming. As a consequence, we propose a novel iPS derivation protocol including a sequential treatment with recombinant Netrin1 that greatly facilitates the generation of mouse and human iPS cells. RNA-sequencing of mouse embryonic fibroblasts (passage 2 and passage 4), mouse pre-iPS cells (passage 5 and passage 25), 1 clone of control iPS (passage 5 and passage 25) and 2 independent clones of "Netrin-1 derived" iPS cells (passage 5 and passage 25). For this analysis, mouse iPS cell lines were grown in KSR+LIF media.

Transcriptional analysis of iPSCs during cellular reprogramming using RNA FACS

Project description:Mouse induced pluripotent stem cells (iPSCs) were derived from embryonic fibroblasts by overexpressing the Yamanaka factors Oct4, Sox2, Klf4 and c-Myc for 32 consecutive days. iPSCs were isolated by RNA FACS (for endogenous Sox2) from a heterogeneous reprogramming culture and transcriptionally compared with (1) iPSCs stabilized in 2i medium (iPS-2i) and (2) iPSCs stabilized in co-culture with mouse embryonic fibroblasts (iPS-MEF)

Reprogramming of fibroblasts from Fragile-X patients to induced pluripotent stem cells (iPS) with defined factors

Project description:Human iPS cells derived from normal and Fragile-X fibroblasts in order to assess the capability of Fragile-X iPS cells to be used as a model for different aspects of Fragile-X syndrome. Microarry analysis used to compare global gene expression between human ES cells, the normal and the mutant iPS cells and the original fibroblasts, to demonstrate that the overall reprogramming process succeeded, and that the FX-iPS cells are fully reprogrammed cells.

Reprogramming of prostate cancer-associated stromal cells

Project description:CD90+ prostate cancer-associated (CP) stromal cells represent a disease cell type found only in tumor tissue. Genetic reprogramming by induced pluripotent stem (iPS) cell technology might be used to “normal gene expression of diseased cells thereby providing a cure. The resultant iPS cells would no longer express the disease program, and, like stem cells, might respond to normal differentiative signaling. Thus, CP stromal cells, isolated from tumor tissue and cultured in vitro, were transfected with POU5F1/LIN28/NANOG/SOX2 lentiviral vectors. iPS cells were obtained at a frequency of 10^4. Transcriptome analysis showed an almost complete match in gene expression between the iPS cells and human embryonic stem cells. Genes of CP stromal cells were fully inactivated.

Role of the reprogramming factors in inducing pluripotency

Project description:Induced pluripotent stem (iPS) cells can be obtained from fibroblasts by expression of Oct4, Sox2, Klf4, and c-Myc. To determine how these factors induce this change in cell identity, we carried out genomewide promoter analysis of their binding in iPS and partially reprogrammed cells. Most targets in iPS cells are shared with ES cells and the factors cooperate to activate the ES-like expression program. In partially reprogrammed cells, genes bound by c-Myc have achieved a more ES-like binding and expression pattern. In contrast, genes that are co-bound by Oct4, Sox2, and Klf4 in ES cells and that encode pluripotency regulators show severe lack of both binding and transcriptional activation. Among the factors, c-Myc has a pivotal effect on the initiation of the ES transcription program, including the repression of fibroblast-specific genes. Our analysis begins to unravel how the four factors function together and suggests a temporal and separable order of their effects during reprogramming. For genome wide expression analysis: A. ES/iPS/partial iPS cells were analyzed in duplicates from 2 different cell lines (e.g four samples per cell type) B. tet inducible factors (tetO/tetS/tetC/tetK) were analyzed individually, a control was an uninduced tet line. C. OCK expression was performed in duplicate with 2 different clones. For genome wide location analysis (ChIP-chip): Oct4/Sox2/c-Myc/Klf4 were performed with biological duplicates (2 clonally isolated iPS/partial iPS lines and ES cells were performed with v6.5 and E14 cell lines)
