Unraveling cartilage degeneration through synergistic effects of hydrostatic pressure and biomimetic temperature increase

Dominique Pioletti, Peyman Karami, Naser Nasrollahzadeh Mamaghani, Theofanis Stampoultzis, Yanheng Guo, Vijay Kumar Rana

Cartilage degeneration, typically viewed as an irreversible, vicious cycle, sees a significant reduction in two essential biophysical cues: the well-established hydrostatic pressure (HP) and the recently discovered transient temperature increase. Our study ...

PEG/HA Hybrid Hydrogels for Biologically and Mechanically Tailorable Bone Marrow Organoids

Nicolas Antoine Vincent Broguiere, Martin Ehrbar, Queralt Vallmajó Martín

Bone marrow (BM) organoids provide powerful tools to study the vital interplay between the BM microenvironment and resident cells. Current biomaterials, however, are limited in terms of versatility for independently studying the biochemical and biophysical ...

Tumour exosomal CEMIP protein promotes cancer cell colonization in brain metastasis

Etienne Meylan, Loïc Steiner, Yuan Liu, Gonçalo Rodrigues

The development of effective therapies against brain metastasis is currently hindered by limitations in our understanding of the molecular mechanisms driving it. Here we define the contributions of tumour-secreted exosomes to brain metastatic colonization ...

An All-Organic Elastomeric Electret Composite

Dragan Damjanovic, Frank Nüesch, Yee Song Ko

Copolymer nanoparticles with a highly polar repeating unit are blended in an elastic matrix and poled at elevated temperatures. The composite exhibits piezoelectricity due to the overall polarization imparted by the particles, which can be easily modulated ...

Microcomputed Tomography Technique for In Vivo Three-Dimensional Fat Tissue Volume Evaluation After Polymer Injection

Harm-Anton Klok, Ioana Konz

Tissue engineering technologies are new and promising techniques in fat tissue reconstruction. However, to assess their efficacy before any clinical application, in vivo experiments are mandatory. This study assesses whether microcomputed tomography (CT) s ...

Coating nanocarriers with hyaluronic acid facilitates intravitreal drug delivery for retinal gene therapy

Hendrik Georges Deschout

Retinal gene therapy could potentially affect the lives of millions of people suffering from blinding disorders. Yet, one of the major hurdles remains the delivery of therapeutic nucleic acids to the retinal target cells. Due to the different barriers that ...

Defining the role of common variation in the genomic and biological architecture of adult human height

Jiancheng Yang, Murielle Bochud, Zhaoming Wang

Using genome-wide data from 253,288 individuals, we identified 697 variants at genome-wide significance that together explained one-fifth of the heritability for adult height. By testing different numbers of variants in independent studies, we show that th ...

Living-Engineered Valves for Transcatheter Venous Valve Repair

Peter Modregger, Marco Stampanoni

Background: Chronic venous insufficiency (CVI) represents a major global health problem with increasing prevalence and morbidity. CVI is due to an incompetence of the venous valves, which causes venous reflux and distal venous hypertension. Several studies ...

Intrinsic viscoelasticity increases temperature in knee cartilage under physiological loading

Dominique Pioletti, Philippe Abdel Sayed, Mohamadreza Nassajian Moghadam

Metabolism of proteoglycans and hyaluronic acid has been shown to be temperature- dependent in cartilage explants, with optimal anabolic effects between 36 1C and 38 1C. At rest, the temperature of human knee has a value of around 33 1C. We aim to show in ...

Improving the osteogenic potential of BMP-2 with hyaluronic acid hydrogel modified with integrin-specific fibronectin fragment

Jeffrey Alan Hubbell, Mikaël Martino

While human bone morphogenetic protein-2 (rhBMP-2) is a promising growth factor for bone regeneration, its clinical efficacy has recently shown to be below expectation. In order to improve the clinical translation of rhBMP-2, there exists strong motivation ...
