First Advanced Bilayer Scaffolds for Tailored Skin Tissue Engineering Produced via Electrospinning and Melt Electrowriting

In vitro skin models are validated methods for screening cosmetics and pharmaceuticals, but still have limitations. The bilayer poly(epsilon-caprolactone) scaffold/membrane model described here overcomes some of these deficits by integrating a solution ele ...

Structure and regulation of the myotonic dystrophy kinase-related Cdc42-binding kinase

Charlotte Julie Caroline Gehin

Protein kinases of the dystonia myotonica protein kinase (DMPK) family are critical regulators of actomyosin contractility in cells. The DMPK kinase MRCK1 is required for the activation of myosin, leading to the develop-ment of cortical tension, apical con ...

Role of Minimum Adhesive Wear Particle Size in Third-Body Layer Properties

Jean-François Molinari, Son-Jonathan Pham-Ba

We employ a novel discrete element method (DEM) force formulation to simulate adhesive wear and assess the effects of material and loading parameters on the properties of the third-body layer (TBL) formed during sliding motion. The study emphasizes the rol ...

Reanalysis of mtDNA mutations of human primordial germ cells (PGCs) reveals NUMT contamination and suggests that selection in PGCs may be positive

Konstantin Popadin

The resilience of the mitochondrial genome (mtDNA) to a high mutational pressure depends, in part, on negative purifying selection in the germline. A paradigm in the field has been that such selection, at least in part, takes place in primordial germ cells ...

An automated do-it-yourself system for dynamic stem cell and organoid culture in standard multi-well plates

Matthias Lütolf, Sebastian Maerkl, Hao-An Hsiung, Zoe Newell Swank, Stefano Davide Vianello, Julia Tischler

We present a low-cost, do-it-yourself system for complexmammalian cell culture under dynamically changing medium formulations by integrating conventional multi-well tissue culture plates with simple microfluidic control and system automation. We demonstrat ...

In vitro endoderm emergence and self-organisation in the absence of extraembryonic tissues and embryonic architecture

Stefano Davide Vianello

In humans, mice, and other mammals key internal organs such as the gut, the lungs, the pancreas, and the liver all derive from the same embryonic tissue: the endoderm. The development of all of these structures thus depends on a same set of early cells, an ...

Differential impact of TGF beta/SMAD signaling activity elicited by Activin A and Nodal on endoderm differentiation of epiblast stem cells

Pierre Osteil

Allocation of cells to an endodermal fate in the gastrulating embryo is driven by Nodal signaling and consequent activation of TGF beta pathway. In vitro methodologies striving to recapitulate the process of endoderm differentiation, however, use TGF beta ...

Preparation of Single-Somite Explants from Zebrafish Embryos

Andrew Charles Oates, Sundar Ram Naganathan

The body axis of vertebrate embryos is periodically subdivided into 3D multicellular units called somites. While genetic oscillations and molecular prepatterns determine the initial length-scale of somites, mechanical processes have been implicated in sett ...

Human reproduction is regulated by retrotransposons derived from ancient Hominidae-specific viral infections

Didier Trono, Julien Paul André Pontis, Yu Tao

The transcription factor network required for primordial germ cell (PGC) specification is known to diverge in mammals. Here the authors show that hominidae-specific transposable element (TE) LTR5Hs becomes transcriptionally active during PGC specification, ...

Method for labelling a device and devices obtanaible therefrom

Nicolas Vachicouras, Florian Dylan Fallegger, Ludovic Serex

Disclosed herein is a method for labelling a portion of a device, said method comprising the steps of providing a first substrate layer of a transparent or translucent material, depositing a first coloured material onto said first substrate layer in a labe ...
