Multimodal characterization of murine gastruloid development
Matthias Lütolf, Alexandre Gauthier Aurèle Mayran, Stefano Davide Vianello, Raphaël Ortiz
Gastruloids are 3D structures generated from pluripotent stem cells recapitulating fundamental principles of embryonic pattern formation. Using single-cell genomic analysis, we provide a resource mapping cell states and types during gastruloid development ...
CELL PRESS2023Targeted search for scaling genes reveals matrix metalloproteinase 3 as a scaler of the dorsal-ventral pattern in Xenopus laevis embryos
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 ...
2022In vitro endoderm emergence and self-organisation in the absence of extraembryonic tissues and embryonic architecture
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 ...
EPFL2022An 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 ...
2022KRAB zinc finger protein-mediated control of transposon-embedded regulatory sequences from human germline to early embryos
Transposable elements (TEs), also called jumping genes, are genetic elements capable of changing their position within the genome of their host. They make up large fractions of genomes, including 45% of human DNA content, according to current estimates.
S ...
EPFL2021In vitro modeling of early mouse development
Previous attempts to recapitulate embryogenesis in a developmentally relevant context started with aggregates composed of a few thousand ESCs, termed embryoid bodies (EB), that upon induction of differentiation reveal a surprising level of autonomous cell ...
EPFL2020Patterning and mechanics of somite boundaries in zebrafish embryos
Andrew Charles Oates, Sundar Ram Naganathan
The body axis of vertebrates is subdivided into repetitive compartments called somites, which give rise primarily to the segmented architecture of the musculoskeletal system in the adult body. Somites form in a sequential and rhythmic manner in embryos and ...
2020Blind killing of both male and female Drosophila embryos by a natural variant of the endosymbiotic bacterium Spiroplasma poulsonii
Bruno Lemaitre, Samuel Rommelaere, Florent François Masson, Juan Camilo Paredes Escobar, Mario Gonzalo Garcia Arraez
Spiroplasma poulsonii is a vertically transmitted endosymbiont of Drosophila melanogaster that causes male-killing, that is the death of infected male embryos during embryogenesis. Here, we report a natural variant of S. poulsonii that is efficiently verti ...
WILEY2020Understanding 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 ...
2019Multi-axial self-organization properties of mouse embryonic stem cells into gastruloids
Denis Duboule, Matthias Lütolf, Anne-Catherine Cossy, Leonardo Beccari, Mehmet Ugur Girgin, 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 ...
