SUMMARY:Institut Jacques Monod seminar - Chloé Roffay
DESCRIPTION:Invited by the Ribes/Nedelec\, Chloé Roffay (Institute of Molecular Pathology (IMP)) will present an Institut Jacques Monod seminar on the theme: \nUncovering the forces driving fate and form of amnion in human gastrula models \nAbstract: \nExtraembryonic tissues provide key molecular signals and mechanical support to the growing embryo. For instance\, the extraembryonic amnion\, which forms a fluid-filled sac surrounding the embryo\, was recently shown to trigger germ layer specification during gastrulation\, by secreting BMP ligands. Despite the key roles of extraembryonic tissues in embryo development\, little is still known regarding their molecular and biophysical programs\, particularly in human. Using a 2D stem cell-based model of human gastrulation\, termed gastruloid discs\, we found that amnion cells undergo a sharp columnar-to-squamous transition concomitantly with fate specification. Via biophysical modelling\, direct force measurements\, pharmacological and genetic perturbations\, we showed that this morphogenetic transition is amnion-intrinsic and it is driven by active wetting\, i.e. a transition from tensile to adhesion-dominated cellular states. Molecularly\, active wetting is implemented via a rewiring of cytoskeleton composition\, from actomyosin to keratin-based cytoskeletal networks\, akin to a bistable toggle-switch in gene regulatory networks. Strikingly\, blocking shape changes at the colony edge results both in defective cellular states in the amnion and impaired gastruloid disc morphogenesis within the embryonic compartment. Together\, our findings establish that a cytoskeletal toggle switch couples fate specification to tissue architecture in the human amnion and suggest an unexpectedly active mechanical role for extraembryonic tissues in shaping the embryo proper.

SUMMARY:Paris Postdoc Seminar - Sophie Peron
DESCRIPTION:Invited by the Institut Jacques Monod\, Sophie Peron ( Institut Imagine\, Team somatic mosaicism in neurodevelopment and disease\, Paris) will present a Paris Postdoc seminar on the theme: \nCoordination between cell cycle and differentiation in planarian stem cells \nAbstract: \nPlanarians have extensive regenerative abilities fuelled by a population of adult stem cells. Those cells also constantly proliferate and differentiate into dozens of different cell types to maintain tissue homeostasis. However\, how cell fate acquisition is coordinated with cell cycle progression remains poorly understood. We choose to address this question in Schmidtea mediterranea using single cell transcriptomics. We generated scRNA-seq datasets from cells enriched for 2C or 4C DNA content and from animals subjected to RNAi against the cell cycle regulators cdh1 and h2b. Our analyses show that progenitor populations across multiple lineages contain actively cycling cells and that lineage commitment occurs at different stages depending on the cell type. Comparative analyses reveal that Schmidtea possesses a simplified repertoire of canonical cell cycle regulators\, consistent with a central role for cdh1 in controlling cell cycle exit. Functional perturbation of cdh1 demonstrates that cell cycle exit is needed for differentiation but not for lineage specification. Together\, these findings provide new insights into how cell cycle regulation is coordinated with lineage commitment and differentiation in planarian stem cells.

SUMMARY:Institut Jacques Monod seminar - Jens Januschke
DESCRIPTION:Invited by the Guichet lab\, Jens Januschke ( Faculty of Life at the University of Dundee\, Scotland\, UK) will present an Institut Jacques Monod on the theme: \nWhen size determines fate: rethinking asymmetric stem cell division of neural stem cells of the fly \nAbstract: \nHow does a stem cell produce two daughters with different identities? Classical models emphasise that in intrinsically controlled asymmetric cell division\, unequal inheritance of molecules can determine fate\, ensuring for instance in some systems that one daughter retains stem cell identity while the other embarks on differentiation. But what if something as simple as cell size could override these molecular instructions? \nAsymmetric cell division is a fundamental mechanism of development and tissue homeostasis. In Drosophila neural stem cells\, this process generates daughters that differ in fate but also dramatically in size. Understanding how this physical asymmetry emerges reveals an intricate interplay between cell polarity\, cortical mechanics and membrane dynamics. Spatially controlled actomyosin contractility and local membrane expansion work together to shape dividing cells\, translating molecular organisation into differences in daughter-cell size. \nIntriguingly\, cell size is more than a passive consequence of asymmetric division. It can actively influence developmental decisions\, even challenging the instructions provided by inherited fate determinants. This raises the possibility that a cell’s physical characteristics are integral to how its identity is established and maintained. \nIn this seminar I will summarise our findings and sketch our direction of travel on the regulation of cell size asymmetry and its contribution on cell fate. \n  \nJens Januschke is joint Head of Molecular\, Cell & Developmental Biology in the Faculty of Life at the University of Dundee. He studied at the University of Cologne and obtained his PhD in genetics from the University of Paris VI before joining the Institute for Research in Biomedicine in Barcelona as a postdoc. Jens started his independent research at the University of Dundee for which he was awarded a Sir Henry Dale fellowship in 2013. In 2023 Jens was awarded a personal chair in Developmental Cell Biology at the University of Dundee. \nHis group is interested in fundamental aspects of cell function during development. He uses Drosophila as a model system with a focus on epithelial biology and epithelial derived asymmetrically dividing neural stem cells of the developing central nervous system. His group uses genetics\, chemical genetics and live cell imaging to unravel principles of how the cell polarity machinery controls epithelial mechanics as well as cell fate decisions in the developing nervous system.
