Enhancing Robustness of Adhesive Hydrogels through PEG-NHS Incorporation

Dominique Pioletti, François Gorostidi, Yanheng Guo, Theofanis Stampoultzis, Vijay Kumar Rana, Ece Mailand

Tissue wounds are a significant challenge for the healthcare system, affecting millions globally. Current methods like suturing and stapling have limitations as they inadequately cover the wound, fail to prevent fluid leakage, and increase the risk of infe ...

Non-invasive investigation of the morphology and optical properties of the upside-down jellyfish Cassiopea with optical coherence tomography

Anders Meibom, Niclas Heidelberg Lyndby, Sandrine Denise Françoise Bessette

The jellyfish Cassiopea largely cover their carbon demand via photosynthates produced by microalgal endosymbionts, but how holobiont morphology and tissue optical properties affect the light microclimate and symbiont photosynthesis in Cassiopea remain unex ...

A model for 3D deformation and reconstruction of contractile microtissues

Mahmut Selman Sakar, Jaemin Kim, Erik Mailand, Nikolaos Bouklas

Tissue morphogenesis and regeneration are essentially mechanical processes that involve coordination of cellular forces, production and structural remodeling of extracellular matrix (ECM), and cell migration. Discovering the principles of cell–ECM interact ...

Method and system for analysis of organic material by auto-cathodoluminescence

Hans Mattias Larsson, Marcin Stefan Zielinski

Analyzing isolated collagen gel samples of a rat-tail and bovine hide, we demonstrated in situ detection of spectrally deconvoluted auto-cathodoluminescence signatures of specific molecular content with precise spatial localization over a maximum field of ...

Label-Free Quantification Proteomics for the Identification of Mesenchymal Stromal Cell Matrisome Inside 3D Poly(Ethylene Glycol) Hydrogels

Matthias Lütolf, Yannick Robert Devaud

Cells modulate the functional properties of their environment by depositing extracellular matrix (ECM) proteins during biological processes in vivo and in vitro. Despite the ECMs central role in tissue formation, its quantification in hydrogels like Matrig ...

Characterization of a B16-F10 melanoma model locally implanted into the ear pinnae of C57BL/6 mice

Esra Güç

The common experimental use of B16-F10 melanoma cells focuses on exploring their metastatic potential following intravenous injection into mice. In this study, B16-F10 cells are used to develop a primary tumor model by implanting them directly into the ear ...

Micromotion-induced peri-prosthetic fluid flow around a cementless femoral stem

Dominique Pioletti, Alexandre Terrier, Valérie Hélène Emilie Malfroy Camine

Micromotion-induced interstitial fluid flow at the bone-implant interface has been proposed to play an important role in aseptic loosening of cementless implants. High fluid velocities are thought to promote aseptic loosening through activation of osteocla ...

Alignment of collagen fiber in knitted silk scaffold for functional massive rotator cuff repair

Dominique Pioletti, Ting Zhu

Rotator cuff tear is one of the most common types of shoulder injuries, often resulting in pain and physical debilitation. Allogeneic tendon-derived decellularized matrices do not have appropriate pore size and porosity to facilitate cell infiltration, whi ...

Quantitative telomeric chromatin isolation protocol for human cells

Joachim Lingner, Jana Majerská, Sophie Redon

The ends of eukaryotic chromosomes, known as telomeres, consist of repetitive DNA sequences, multiple proteins and noncoding RNAs. Telomeres are dynamic structures that play crucial roles as guardians of genome stability and tumor suppressors. Defects in t ...

Micromotion and fluid flow around cementless femoral components in total hip arthroplasty

Valérie Hélène Emilie Malfroy Camine

Cementless total hip arthroplasty is a highly successful and reliable procedure to restore joint function and reduce pain in patients with severe osteoarthritis. Nevertheless, despite the technical advances over the last decades in the development of cemen ...

Remote Control of Intestinal Stem Cell Activity by Haemocytes in Drosophila

Bruno Lemaitre, Jean Philippe Boquete, Sveta Chakrabarti, Jan Paul Dudzic, Xiaoxue Li

The JAK/STAT pathway is a key signaling pathway in the regulation of development and immunity in metazoans. In contrast to the multiple combinatorial JAK/STAT pathways in mammals, only one canonical JAK/STAT pathway exists in Drosophila. It is activated by ...

Cell proliferation and migration during early development of a symbiotic scleractinian coral

Anders Meibom, Isabelle Domart-Coulon, Agathe Eliette Marie Lecointe

In scleractinian reef-building corals, patterns of cell self-renewal, migration and death remain virtually unknown, limiting our understanding of cellular mechanisms underlying initiation of calcification, and ontogenesis of the endosymbiotic dinoflagellat ...

A Current View of Functional Biomaterials for Wound Care, Molecular and Cellular Therapies

Francesco Piraino

The intricate process of wound healing involves activation of biological pathways that work in concert to regenerate a tissue microenvironment consisting of cells and external cellular matrix (ECM) with enzymes, cytokines, and growth factors. Distinct stag ...

Long-lasting fibrin matrices ensure stable and functional angiogenesis by highly tunable, sustained delivery of recombinant VEGF(164)

Jeffrey Alan Hubbell, Veronica Sacchi

Clinical trials of therapeutic angiogenesis by vascular endothelial growth factor (VEGF) gene delivery failed to show efficacy. Major challenges include the need to precisely control in vivo distribution of growth factor dose and duration of expression. Re ...

Optimization of operation conditions for the startup of aerobic granular sludge reactors biologically removing carbon, nitrogen, and phosphorous

Christof Holliger, Samuel Lochmatter

The transformation of conventional flocculent sludge to aerobic granular sludge (AGS) biologically removing carbon, nitrogen and phosphorus (COD, N, P) is still a main challenge in startup of AGS sequencing batch reactors (AGS-SBRs). On the one hand a rapi ...

Proteolytic Processing Regulates Placental Growth Factor Activities

Jeffrey Alan Hubbell, Stéphanie Elisabeth Metzger

Placental growth factor (PlGF) is a critical mediator of blood vessel formation, yet mechanisms of its action and regulation are incompletely understood. Here we demonstrate that proteolytic processing regulates the biological activity of PlGF. Specificall ...
