Proliferation-driven mechanical compression induces signalling centre formation during mammalian organ development

Localized sources of morphogens, called signalling centres, play a fundamental role in coordinating tissue growth and cell fate specification during organogenesis. However, how these signalling centres are established in tissues during embryonic developmen ...

Regulation and function of a hemicleaved Activin-A processing intermediate in melanoma

Manon Bulliard

Activin-A is a Transforming Growth Factor-B (TGFB)-related cytokine that regulates various biological processes including cell proliferation and differentiation through autocrine, paracrine or endocrine signaling. Activin-A expression is upregulated in mul ...

Premature Vertebral Mineralization in hmx1-Mutant Zebrafish

H6 family homeobox 1 (HMX1) regulates multiple aspects of craniofacial development, and mutations in HMX1 are linked to an ocular defect termed oculoauricular syndrome of Schorderet-Munier-Franceschetti (OAS) (MIM #612109). Recently, additional altered oro ...

LTP of inhibition at PV interneuron output synapses requires developmental BMP signaling

Ralf Schneggenburger, Christopher Clark, Denys Osypenko, Evan Dean Vickers

Parvalbumin (PV)-expressing interneurons (PV-INs) mediate well-timed inhibition of cortical principal neurons, and plasticity of these interneurons is involved in map remodeling of primary sensory cortices during critical periods of development. To assess ...

Tp63-expressing adult epithelial stem cells cross lineages boundaries revealing latent hairy skin competence

Yann Barrandon, Ariane Rochat, Stéphanie Claudinot, Paola Bonfanti, Christèle Gonneau, Daniel-Alexandre Littman

The formation of hair follicles, a landmark of mammals, requires complex mesenchymal-epithelial interactions and it is commonly believed that embryonic epidermal cells are the only cells that can respond to hair follicle morphogenetic signals in vivo. Here ...

Improving Inter-Laboratory Reproducibility in Measurement of Biochemical Methane Potential (BMP)

Christof Holliger

Biochemical methane potential (BMP) tests used to determine the ultimate methane yield of organic substrates are not sufficiently standardized to ensure reproducibility among laboratories. In this contribution, a standardized BMP protocol was tested in a l ...

Engineered signaling centers for the spatially controlled patterning of human pluripotent stem cells

Matthias Lütolf, Felix Naef, Yoji Tabata, Eric Paquet, François Réal Rivest, Ambroise Roger Vuaridel, Andrea Manfrin

Signaling centers, localized groups of cells that secrete morphogens, play a key role in early development and organogenesis by orchestrating spatial cell fate patterning. Here we present a microfluidic approach that exposes human pluripotent stem cell (hP ...

Endothelial Calcineurin Signaling Restrains Metastatic Outgrowth by Regulating Bmp2

Nadine Fournier, Mauro Delorenzi, Sina Nassiri, Borja Prat Luri, Laureline Wetterwald

Calcineurin/NFAT signaling is active in endothelial cells and is proposed to be an essential component of the tumor angiogenic response. Here, we investigated the role of endothelial calcineurin signaling in vivo in physiological and pathological angiogene ...

Role of BMP Signaling for the Formation of Auditory Brainstem Nuclei and Large Auditory Relay Synapses

Ralf Schneggenburger, Christopher Clark, Elin Kristina Kronander

Large excitatory synapses are found at specific points in the neuronal circuits of the auditory brainstem, to enable fast information transfer and the preservation of acoustic timing information. The extracellular cues and signaling mechanisms that lead to ...

Quantitative single cell dynamics of signaling and transcriptional response in mammalian cells

Onur Tidin

Cells live in ever-changing environments, thereby facing a variety of dynamic environmental signals. Environmental stimuli elicit intracellular responses through signaling pathways, which converge on transcriptional activation or repression of target genes ...

Genetic dissection of the role of BMP signaling for the development of the auditory brainstem nuclei and the large calyx of Held synapse

Elin Kristina Kronander

Synapses are key elements for communication within the complex network of neurons that make up our brain. Interestingly, synaptic connections can differ greatly in form and function, depending on the specific circuit into which they are embedded. In this P ...

Towards a standardization of biomethane potential tests

Christof Holliger, Gabrielle Hack, Jing Liu

Production of biogas from different organic materials is a most interesting source of renewable energy. The biomethane potential (BMP) of these materials has to be determined to get insight in design parameters for anaerobic digesters. Although several nor ...

Engineering growth factors for regenerative medicine applications

Jeffrey Alan Hubbell, Priscilla Suhasna Maithili Briquez

Growth factors are important morphogenetic proteins that instruct cell behavior and guide tissue repair and renewal. Although their therapeutic potential holds great promise in regenerative medicine applications, translation of growth factors into clinical ...

Loss of MITF expression during human embryonic stem cell differentiation disrupts retinal pigment epithelium development and optic vesicle cell proliferation

Bernard Schneider

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 ...

Control of Mitochondrial pH by Uncoupling Protein 4 in Astrocytes Promotes Neuronal Survival

Pierre Magistretti, Hélène Danielle Perreten Lambert, Sylvain Eric Lengacher, Manuel Raphael Zenger, Jean-Yves Chatton

Brain activity is energetically costly and requires a steady and highly regulated flow of energy equivalents between neural cells. It is believed that a substantial share of cerebral glucose, the major source of energy of the brain, will preferentially be ...

BMP signaling specifies the development of a large and fast CNS synapse

Graham Knott, Ralf Schneggenburger, Enida Gjoni, Le Xiao, Elin Kristina Kronander

excitatory synapses with multiple active zones ensure reliable and fast information transfer at specific points in neuronal circuits. However, the mechanisms that determine synapse size in CNS circuits are largely unknown. Here we use the calyx of Held syn ...
