First Advanced Bilayer Scaffolds for Tailored Skin Tissue Engineering Produced via Electrospinning and Melt Electrowriting

In vitro skin models are validated methods for screening cosmetics and pharmaceuticals, but still have limitations. The bilayer poly(epsilon-caprolactone) scaffold/membrane model described here overcomes some of these deficits by integrating a solution ele ...

Sodium thiosulfate, a source of hydrogen sulfide, stimulates endothelial cell proliferation and neovascularization

Georges Wagnières, Jaroslava Joniová, Séverine Marguerite Urfer

Therapies to accelerate vascular repair are currently lacking. Pre-clinical studies suggest that hydrogen sulfide (H2S), an endogenous gasotransmitter, promotes angiogenesis. Here, we hypothesized that sodium thiosulfate (STS), a clinically relevant source ...

Apelin-driven endothelial cell migration sustains intestinal progenitor cells and tumor growth

Michele De Palma, Nadine Fournier, Sina Nassiri, Stefanie Siegert, Mauro Delorenzi, Mario Leonardo Squadrito, Pascale Anderle Pedone, Simone Ragusa, François Renevey

Stem and progenitor cells residing in the intestinal crypts drive the majority of colorectal cancers (CRCs), yet vascular contribution to this niche remains largely unexplored. Vascular endothelial growth factor A (VEGFA) is a key driver of physiological a ...

Impact of atrial fibrillation on left atrium haemodynamics: A computational fluid dynamics study

Alfio Quarteroni, Luca Dede'

We analyse the haemodynamics of the left atrium, highlighting differences between healthy individuals and patients affected by atrial fibrillation. The computational study is based on patient-specific geometries of the left atria to simulate blood flow dyn ...

The angiopoietin-Tie2 pathway regulates Purkinje cell dendritic morphogenesis in a cell-autonomous manner

Michele De Palma

Neuro-vascular communication is essential to synchronize central nervous system development. Here, we identify angiopoietin/Tie2 as a neuro-vascular signaling axis involved in regulating dendritic morphogenesis of Purkinje cells (PCs). We show that in the ...

Bioprinting of Cartilaginous Auricular Constructs Utilizing an Enzymatically Crosslinkable Bioink

Nicolas Antoine Vincent Broguiere, Philipp Fisch

Bioprinting of functional tissues could overcome tissue shortages and allow a more rapid response for treatments. However, despite recent progress in bioprinting, and its outstanding ability to position cells and biomaterials in a precise 3D manner, its su ...

Morphogenesis Guided by 3D Patterning of Growth Factors in Biological Matrices

Matthias Lütolf, Nicolas Antoine Vincent Broguiere, Riccardo Rizzo

Three-dimensional (3D) control over the placement of bioactive cues is fundamental to understand cell guidance and develop engineered tissues. Two-photon patterning (2PP) provides such placement at micro- to millimeter scale, but nonspecific interactions b ...

The heparin binding domain of von Willebrand factor binds to growth factors and promotes angiogenesis in wound healing

Matthias Lütolf, Jeffrey Alan Hubbell, Yoji Tabata, Jun Ishihara, Kazuto Fukunaga

During wound healing, the distribution, availability, and signaling of growth factors (GFs) are orchestrated by their binding to extracellular matrix components in the wound microenvironment. Extracellular matrix proteins have been shown to modulate angiog ...

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 ...

Anti-angiogenic immunotherapy for lung cancer

Ece Kadioglu

Lung cancer is the leading cause of cancer-associated deaths worldwide. Platinum-based chemotherapy is the most common therapeutic approach in advanced non-small cell lung cancer (NSCLC), particularly for tumors that carry non-druggable activating mutation ...
