Metabolic and transcriptomic profiles of glioblastoma invasion revealed by comparisons between patients and corresponding orthotopic xenografts in mice

Cristina Ramona Cudalbu Moldovan, Lijing Xin, Mario Gaetano Lepore, Marta Lai

The invasive behavior of glioblastoma, the most aggressive primary brain tumor, is considered highly relevant for tumor recurrence. However, the invasion zone is difficult to visualize by Magnetic Resonance Imaging (MRI) and is protected by the blood brain ...

Evolutionary history expands the range of signaling interactions in hybrid multikinase networks

Anne-Florence Raphaëlle Bitbol

Two-component systems (TCSs) are ubiquitous signaling pathways, typically comprising a sensory histidine kinase (HK) and a response regulator, which communicate via intermolecular kinase-to-receiver domain phosphotransfer. Hybrid HKs constitute non-canonic ...

Passivating Polysilicon Recombination Junctions for Crystalline Silicon Solar Cells

Christophe Ballif, Franz-Josef Haug, Aïcha Hessler-Wyser, Quentin Thomas Jeangros, Andrea Ingenito, Mario Joe Lehmann, Philippe Wyss, Audrey Marie Isabelle Morisset

Polysilicon recombination junctions whose n-type bottom layers double as a passivating contact to the silicon surface are investigated. Such recombination junctions are a key element in the interconnection of tandem devices with a silicon bottom cell, and ...

Single-cell lipidomics reveals a role for cell-to-cell sphingolipid heterogeneity in fibroblast activation

Laura Capolupo

Cell-to-cell variability plays a key role in tissue patterning by setting initial asymmetry that primes cell fate decisions. Fluctuations in the activity of regulatory molecules can commit individual cells to divergent differentiation pathways, and cell-to ...

Co-regulation of endothelial and myogenic cell fates through intercellular crosstalk in skeletal muscle

Umji Lee

Skeletal muscle is one of the most dynamic organs in the human body, which has a vigorous potential to regenerate and adapt to environmental changes. Depending on environments, skeletal muscle enables essential life activities to survive by controlling mov ...

Active biomaterials for mechanobiology

Mahmut Selman Sakar, Berna Ayse Özkale Edelmann

Active biomaterials offer novel approaches to study mechanotransduction in mammalian cells. These material systems probe cellular responses by dynamically modulating their resistance to endogenous forces or applying exogenous forces on cells in a temporall ...

In-flow measurement of cell-cell adhesion using oscillatory inertial microfluidics

Kevin Keim

Multicellular clusters in circulation can exhibit a substantially different function and biomarker significance compared to individual cells. Notably, clusters of circulating tumor cells (CTCs) are much more effective initiators of metastasis than single C ...

Waiting on the Fringe: cell autonomy and signaling delays in segmentation clocks

Andrew Charles Oates

The rhythmic and sequential segmentation of the vertebrate body axis into somites during embryogenesis is governed by a multicellular, oscillatory patterning system called the segmentation clock. Despite many overt similarities between vertebrates, differe ...

Integrin-Mediated Adhesion in the Unicellular Holozoan Capsaspora owczarzaki

Omaya Pierre Dudin

In animals, cell-matrix adhesions are essential for cell migration, tissue organization, and differentiation, which have central roles in embryonic development [1-6]. Integrins are the major cell surface adhesion receptors mediating cell-matrix adhesion in ...

Surface engineering of T cells with polymer nanoparticles to enhance drug delivery to the brain

Markus Schuster

Firstly, this thesis presents the in vivo evaluation of a previously developed model system that utilizes CD4+ TE/M cells decorated with up to 100 polystyrene based nanoparticles per cell by maleimide thiol conjugation. These nanoparticle T-cell conjugates ...
