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 ...
JOURNAL OF VISUALIZED EXPERIMENTS2022Towards engineering an artificial neural tube
In this thesis, I present a self-organizing neural tube organoid that is strikingly similar in morphology, cell-type composition, and patterning to the mouse embryonic neural tube. When exposed to a sequence of epiblast culture conditions and neural differ ...
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 ...
EPFL2020HOX13-dependent chromatin accessibility underlies the transition towards the digit development program
Alexandre Gauthier Aurèle Mayran
Hox genes encode transcription factors (TFs) that establish morphological diversity in the developing embryo. The similar DNA-binding motifs of the various HOX TFs contrast with the wide-range of HOX-dependent genetic programs. The influence of the chromat ...
2020Tail Bud Progenitor Activity Relies on a Network Comprising Gdf11, Lin28, and Hox13 Genes
During the trunk-to-tail transition, axial progenitors relocate from the epiblast to the tail bud. Here, we show that this process entails a major regulatory switch, bringing tail bud progenitors under Gdf11 signaling control. Gdf11 mutant embryos have an ...
CELL PRESS2019Coordinated Hoxd genes expression during embryogenesis is dependent on a strict disposition of genes and polarized regulators within the HoxD cluster
HOX transcription factors determine the identity of body regions along the rostro-caudal axis during bilaterian embryogenesis. In vertebrates Hox genes distinctively lie organized in dense clusters, each typically composed of a dozen paralogous transcripti ...
EPFL2018Glycosphingolipid metabolic reprogramming drives neural differentiation
Giovanni D'Angelo, Riccardo Rizzo
Neural development is accomplished by differentiation events leading to metabolic reprogramming. Glycosphingolipid metabolism is reprogrammed during neural development with a switch from globo- to ganglio-series glycosphingolipid production. Failure to exe ...
2018In vitro modeling of complex microenvironmental regulation of stem cells
Although stem cells hold tremendous potential for clinical applications, their in vitro manipulation remains very challenging. In vivo, stem cells reside in intricate 3D microenvironments, termed niche, in which many local and systemic extrinsic factors ar ...
EPFL2017Loss of MITF expression during human embryonic stem cell differentiation disrupts retinal pigment epithelium development and optic vesicle cell proliferation
Microphthalmia-associated transcription factor (MITF) is a master regulator of pigmented cell survival and differentiation with direct transcriptional links to cell cycle, apoptosis and pigmentation. In mouse, Mitf is expressed early and uniformly in optic ...
Oxford University Press2014Combined function of HoxA and HoxB clusters in neural crest cells
Denis Duboule, Maxence Vieux-Rochas
The evolution of chordates was accompanied by critical anatomical innovations in craniofacial development, along with the emergence of neural crest cells. The potential of these cells to implement a craniofacial program in part depends upon the (non-)expre ...
