ABSTRACT: In order to progress human induced pluripotent stem cells (hiPSCs) towards the clinic, several outstanding questions must be addressed. It is possible to reprogram different somatic cell types into hiPSCs and from studies in the mouse, it appears that an epigenetic memory of the starting cell type is carried over to hiPSCs. However a comprehensive comparative study of the characteristics of these hiPSCs has been missing from the literature. Importantly studies which aimed to address these aspects of hiPSCs have used cells from different patients. In order to avoid this important confounding variable and to keep the genetic background constant, tissue samples were procured from the patients and reprogrammed to iPS cells. The transcriptomes of these iPS cells will be compared. Protocol: primary cultures of cells were reprogrammed to iPS cells. RNA was extracted using a standard column extraction kit.

Genetic background drives transcriptional variation in human induced pluripotent stem cells.

PLoS genetics 20140605 6

Human iPS cells have been generated using a diverse range of tissues from a variety of donors using different reprogramming vectors. However, these cell lines are heterogeneous, which presents a limitation for their use in disease modeling and personalized medicine. To explore the basis of this heterogeneity we generated 25 iPS cell lines under normalised conditions from the same set of somatic tissues across a number of donors. RNA-seq data sets from each cell line were compared to identify the ...[more]

Reprogramming of fibroblasts into induced pluripotent stem cells with Bmi1

Project description:Somatic cells can be reprogrammed into induced pluripotent stem (iPS) cells by Oct4, Sox2, Klf4, plus c-Myc. Recently, Sox2 plus Oct4 were shown to reprogram fibroblasts and Oct4 alone to reprogram mouse and human neural stem cells (NSCs) into iPS cells. Here we report that Bmi1 leads to dedifferentiation of mouse fibroblasts into NSC-like cells and, in combination with Oct4, replaces Sox2, Klf4 and c-Myc during reprogramming fibroblasts to iPS cells. Furthermore, activation of sonic hedgehog signalling (by Shh, purmorphamine, or oxysterol) replaces the effects of Bmi1, and, in combination with Oct4, reprograms mouse embryonic and adult fibroblasts into iPS cells. One-and two-factor iPS cells are similar to mouse embryonic and adult fibroblasts into iPS cells in global gene expression profile, epigenetic status, in vitro and in bibo differentiation into all three ferm layers, as well as teratoma formation and germline transmission in vivo. These data support that fibroblasts can be reprogrammed into iPS cells by Oct4 alone. Total RNAs were isolated from indicated cells and labeled with Cy3. Hybridization was performed once for each sample.

Assessment of genetic and epigenetic variation in human IPS cells

Project description:In order to progress human induced pluripotent stem cells (hiPSCs) towards the clinic, several outstanding questions must be addressed. It is possible to reprogram different somatic cell types into hiPSCs but it is unclear whether some cell types carry through fewer mutations through reprogramming (either due to mutations present in the primary cells, or mutations accumulated during reprogramming). Through in depth analysis of hiPSCs generated from different somatic cells, it will be possible to assess the variation in genetic stability of different cell types.
