Recapitulating macro-scale tissue self-organization through organoid bioprinting

Matthias Lütolf, Moritz Hofer, Mikhail Nikolaev, Jonathan Brassard

A 3D bioprinting approach has been developed to facilitate tissue morphogenesis by directly depositing organoid-forming stem cells in an extracellular matrix, with the ability to generate intestinal epithelia and branched vascular tissue constructs. Biopri ...

In vitro modeling of complex microenvironmental regulation of stem cells

Yoji Tabata

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 ...

Environmental drivers of carbon and nitrogen isotopic signatures in peatland vascular plants along an altitude gradient

Alexandre Buttler, Konstantin Svetlozarov Gavazov, Luca Bragazza

Peatlands are important sinks of atmospheric carbon (C) that, in response to climate warming, are undergoing dynamic vegetation succession. Here we examined the hypothesis that the uptake of nutrients by different plant growth forms (PGFs) is one key mecha ...

Peatland vascular plant functional types affect dissolved organic matter chemistry

Alexandre Buttler, Luca Bragazza, Vincent Eric Jules Jassey, Bjorn Jozef Maria Robroek, Adrian Pulgarin, Remy Jean Henry Albrecht, Samuel Thomas Gabriel Hamard

Northern peatlands are large repositories of carbon. Peatland vascular plant community composition has been functionally associated to a set of biogeochemical processes such as carbon cycling. Yet, we do not fully understand to what extent vascular plant f ...

Experimental warming interacts with soil moisture to discriminate plant responses in an ombrotrophic peatland

Alexandre Buttler, Pierre Rémi Mariotte, Edward Mitchell, Luca Bragazza, Vincent Eric Jules Jassey, Bjorn Jozef Maria Robroek, Cédric Pochelon

QuestionA better understanding of the response of Sphagnum mosses and associated vascular plants to climate warming is relevant for predicting the carbon balance of peatlands in a warmer world. Open-top chambers (OTCs) have been used to investigate the eff ...

Whisking-Related Changes in Neuronal Firing and Membrane Potential Dynamics in the Somatosensory Thalamus of Awake Mice

Carl Petersen

The thalamus transmits sensory information to the neocortex and receives neocortical, subcortical, and neuromodulatory inputs. Despite its obvious importance, surprisingly little is known about thalamic function in awake animals. Here, using intracellular ...

Nitrogen limitation and microbial diversity at the treeline

Alexandre Buttler, Julien Roy, Aurélie Thébault

Tree growth limitation at treeline has mainly been studied in terms of carbon limitation while effects and mechanisms of potential nitrogen (N) limitation are barely known, especially in the southern hemisphere. We investigated how soil abiotic properties ...

Holocene changes in climate and land use drove shifts in the diversity of testate amoebae in a subalpine pond

Mariusz Lamentowicz

Testate amoebae that inhabit peat are sensitive indicators of water table position. In this study, we used testate amoebae in sediments from a mire in the western Alps (Lac du Thyl) to: (1) reconstruct the hydrology of the site over the last 7,000 years, ( ...

Behaviour-dependent recruitment of long-range projection neurons in somatosensory cortex

Bernard Schneider, Stefano Carta

In the mammalian neocortex, segregated processing streams are thought to be important for forming sensory representations of the environment(1,2), but how local information in primary sensory cortex is transmitted to other distant cortical areas during beh ...

Above- and belowground linkages in Sphagnum peatland: climate warming affects plant-microbial interactions

Alexandre Buttler, Edward Mitchell, Vincent Eric Jules Jassey

Peatlands contain approximately one third of all soil organic carbon (SOC). Warming can alter above- and belowground linkages that regulate soil organic carbon dynamics and C-balance in peatlands. Here we examine the multiyear impact of in situ experimenta ...
