Meeting our Makers: Uncovering the cis-regulatory activity of transposable elements using statistical learning

The adaptation of organisms to their environment depends on the innovative potential inherent to genetic variation. In complex organisms such as mammals, processes like development and immunity require tight gene regulation. Complex forms emerge more often ...

Inheritance of H3K9 methylation regulates genome architecture in Drosophila early embryos

Fides Zenk

Constitutive heterochromatin is essential for transcriptional silencing and genome integrity. The establishment of constitutive heterochromatin in early embryos and its role in early fruitfly development are unknown. Lysine 9 trimethylation of histone H3 ( ...

Targeted search for scaling genes reveals matrix metalloproteinase 3 as a scaler of the dorsal-ventral pattern in Xenopus laevis embryos

Daria Korotkova

How embryos scale patterning according to size is still not fully understood. Through in silico screening and analysis of reaction-diffusion systems that could be responsible for scaling, we predicted the existence of genes whose expression is sensitive to ...

Understanding the Mechanobiology of Early Mammalian Development through Bioengineered Models

Matthias Lütolf, Stefano Davide Vianello

Research in developmental biology has been recently enriched by a multitude of in vitro models recapitulating key milestones of mammalian embryogenesis. These models obviate the challenge posed by the inaccessibility of implanted embryos, multiply experime ...

Robust Baseline Measurement for Reliable Fetal Heart Rate Evaluation

Guglielmo Frigo

Cardiotocography is a measurement technique widely adopted to assess fetal well-being during both antepartum and intra-partum stages. It consists of two simultaneously acquired time-series: fetal heart rate and uterine activity. Since visual inspection ana ...

Multi-axial self-organization properties of mouse embryonic stem cells into gastruloids

Denis Duboule, Matthias Lütolf, Leonardo Beccari, Mehmet Ugur Girgin, Anne-Catherine Cossy, Alfonso Martinez Arias

The emergence of multiple axes is an essential element in the establishment of the mammalian body plan. This process takes place shortly after implantation of the embryo within the uterus and relies on the activity of gene regulatory networks that coordina ...

Lab-on-a-chip technologies for manipulation and imaging of C. elegans worms and embryos

Li Dong

The nematode Caenorhabditis elegans is an attractive model organism, owing notably to its short life cycle, genetic tractability, and optical transparency facilitating microscopic observation. This thesis deals with the realization of technological tools f ...

Segmentation of Developing Human Embryo in Time-lapse Microscopy

Mathieu Salzmann

Being able to efficiently segment a developing embryo from background clutter constitutes an important step in automated monitoring of human embryonic cells. State-of-the-art automatic segmentation methods remain ill-suited to handle the complex behavior a ...

Molecular Criteria for Defining the Naive Human Pluripotent State

Didier Trono, Evaristo Jose Planet Letschert, Julien Paul André Pontis, Julien Léonard Duc, Alexandra Iouranova, Marc Samuel Friedli, Michaël Imbeault, Haoyi Wang

Recent studies have aimed to convert cultured human pluripotent cells to a naive state, but it remains unclear to what extent the resulting cells recapitulate in vivo naive pluripotency. Here we propose a set of molecular criteria for evaluating the naive ...

Epiblast-specific loss of HCF-1 leads to failure in anterior-posterior axis specification

Daniel Constam, Winship Herr, Sylvain Frédéric Bessonnard

Mammalian Host-Cell Factor 1 (HCF-1), a transcriptional co-regulator, plays important roles during the cell-division cycle in cell culture, embryogenesis as well as adult tissue. In mice, HCF-1 is encoded by the X-chromosome-linked Hcfc1 gene. Induced Hcfc ...
