Endogenous fluctuations of OCT 4 and SOX 2 bias pluripotent cell fate decisions

David Michael Suter, Cédric Deluz, Andrea Brigitta Alber, Torgil Elias Friman, Subashika Govindan, Daniel Strebinger

SOX2 and OCT4 are pioneer transcription factors playing a key role in embryonic stem (ES) cell self‐renewal and differentiation. How temporal fluctuations in their expression levels bias lineage commitment is unknown. Here, we generated knock‐in reporter f ...

Alternative interaction sites in the influenza A virus nucleoprotein mediate viral escape from the importin-alpha 7 mediated nuclear import pathway

Jaume Bonet Martinez

Influenza A viruses are able to adapt to restrictive conditions due to their high mutation rates. Importin-alpha 7 is a component of the nuclear import machinery required for avian-mammalian adaptation and replicative fitness in human cells. Here, we eluci ...

Difference in suitable mechanical properties of three-dimensional, synthetic scaffolds for self-renewing mouse embryonic stem cells of different genetic backgrounds

Jeffrey Alan Hubbell

We evaluated whether the genetic background of embryonic stem cells (ESCs) affects the properties suitable for three-dimensional (3D) synthetic scaffolds for cell self-renewal. Inbred R1 and hybrid B6D2F1 mouse ESC lines were cultured for 7 days in hydroge ...

Quantitative telomeric chromatin isolation protocol for human cells

Joachim Lingner, Jana Majerská, Sophie Redon

The ends of eukaryotic chromosomes, known as telomeres, consist of repetitive DNA sequences, multiple proteins and noncoding RNAs. Telomeres are dynamic structures that play crucial roles as guardians of genome stability and tumor suppressors. Defects in t ...

Transposable Elements and Their KRAB-ZFP Controllers Regulate Gene Expression in Adult Tissues

Didier Trono, Priscilla Turelli, Sandra Eloise Kjeldsen, Julien Léonard Duc, Michaël Imbeault, Marco Cassano, Gabriela Ecco, Annamaria Kauzlaric, Andrea Coluccio

KRAB-containing zinc finger proteins (KRAB-ZFPs) are early embryonic controllers of transposable elements (TEs), which they repress with their cofactor KAP1 through histone and DNA methylation, a process thought to result in irreversible silencing. Using a ...

Microwell and impedance-based approaches to isolate single cells for life sciences

Georges Muller

Cellular heterogeneity is ubiquitous in any cell population. Understanding these variations is key to answering fundamental questions in immunology, developmental biology, cancer or stem cell biology. For instance, single-cell in vitro and in vivo assays h ...

Concise Reviews: In Vitro-Produced Pancreas Organogenesis Models in Three Dimensions: Self-Organization From Few Stem Cells or Progenitors

Anne Grapin-Botton, Chiara Greggio, Filippo De Franceschi

Three-dimensional models of organ biogenesis have recently flourished. They promote a balance between stem/progenitor cell expansion and differentiation without the constraints of flat tissue culture vessels, allowing for autonomous self-organization of ce ...

Clonal, Self-Renewing and Differentiating Human and Porcine Urothelial Cells, a Novel Stem Cell Population

Jeffrey Alan Hubbell, Peter Frey, Yann Barrandon, Hans Mattias Larsson, François Gorostidi

Although urothelial progenitor-like cells have been described in the human urinary tract, the existence of stem cells remains to be proven. Using a culture system that favors clonogenic epithelial cell growth, we evaluated and characterized clonal human ur ...

Microtechnologies to Map the Fate of Single Stem Cells and their Progeny

Stefan Kobel

Since stem cells have the unique ability to produce more of themselves (i.e. to "self-renew") and to generate specialized tissue cells, they are an ideal source of cells for regenerative medicine and in vitro tissue models. In order to fully exploit this p ...
