Duchemin A-L, Vignes H, Vermot J, 2019, Mechanically activated piezo channels modulate outflow tract valve development through the Yap1 and Klf2-Notch signaling axis, eLife, Vol: 8, Pages: 1-27, ISSN: 2050-084X

Mechanical forces are well known for modulating heart valve developmental programs. Yet, it is still unclear how genetic programs and mechanosensation interact during heart valve development. Here, we assessed the mechanosensitive pathways involved during zebrafish outflow tract (OFT) valve development in vivo. Our results show that the hippo effector Yap1, Klf2, and the Notch signaling pathway are all essential for OFT valve morphogenesis in response to mechanical forces, albeit active in different cell layers. Furthermore, we show that Piezo and TRP mechanosensitive channels are important factors modulating these pathways. In addition, live reporters reveal that Piezo controls Klf2 and Notch activity in the endothelium and Yap1 localization in the smooth muscle progenitors to coordinate OFT valve morphogenesis. Together, this work identifies a unique morphogenetic program during OFT valve formation and places Piezo as a central modulator of the cell response to forces in this process.

Ferreira RR, Pakula G, Klaeyle L, Fukui H, Vilfan A, Supatto W, Vermot Jet al., 2018, Chiral Cilia orientation in the left-right organizer, Cell Reports, Vol: 25, Pages: 2008-2016.e4, ISSN: 2211-1247

Chirality is a property of asymmetry between an object and its mirror image. Most biomolecules and many cell types are chiral. In the left-right organizer (LRO), cilia-driven flows transfer such chirality to the body scale. However, the existence of cellular chirality within tissues remains unknown. Here, we investigate this question in Kupffer’s vesicle (KV), the zebrafish LRO. Quantitative live imaging reveals that cilia populating the KV display asymmetric orientation between the right and left sides, resulting in a chiral structure, which is different from the chiral cilia rotation. This KV chirality establishment is dynamic and depends on planar cell polarity. While its impact on left-right (LR) symmetry breaking remains unclear, we show that this asymmetry does not depend on the LR signaling pathway or flow. This work identifies a different type of tissue asymmetry and sheds light on chirality genesis in developing tissues.

The zebrafish ( Danio rerio) is a powerful vertebrate model to study cellular and developmental processes in vivo. The optical clarity and their amenability to genetic manipulation make zebrafish a model of choice when it comes to applying optical techniques involving genetically encoded photoresponsive protein technologies. In recent years, a number of fluorescent protein and optogenetic technologies have emerged that allow new ways to visualize, quantify, and perturb developmental dynamics. Here, we explain the principles of these new tools and describe some of their representative applications in zebrafish.

The heartbeat and blood flow signal to endocardial cell progenitors through mechanosensitive proteins that modulate the genetic program controlling heart valve morphogenesis. To date, the mechanism by which mechanical forces coordinate tissue morphogenesis is poorly understood. Here we use high-resolution imaging to uncover the coordinated cell behaviours leading to heart valve formation. We find that heart valves originate from progenitors located in the ventricle and atrium that generate the valve leaflets through a coordinated set of endocardial tissue movements. Gene profiling analyses and live imaging reveal that this reorganization is dependent on extracellular matrix proteins, in particular on the expression of fibronectin1b. We show that blood flow and klf2a, a major endocardial flow-responsive gene, control these cell behaviours and fibronectin1b synthesis. Our results uncover a unique multicellular layering process leading to leaflet formation and demonstrate that endocardial mechanotransduction and valve morphogenesis are coupled via cellular rearrangements mediated by fibronectin synthesis.

Live imaging is extremely useful to characterize the dynamics of cellular events in vivo, yet it is limited in terms of spatial resolution. Correlative light and electron microscopy (CLEM) allows combining live confocal microscopy with electron microscopy (EM) for the characterization of biological samples at high temporal and spatial resolution. Here we describe a protocol allowing extracting endothelial cell ultrastructure after having imaged the same cell in its in vivo context through live confocal imaging during zebrafish embryonic development.
