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

Georges Wagnières, Séverine Marguerite Urfer, Jaroslava Joniová

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

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

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 ...

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

Philipp Fisch, Nicolas Antoine Vincent Broguiere

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

Mauro Delorenzi, Laureline Wetterwald, Nadine Fournier, Sina Nassiri, Borja Prat Luri

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 ...

Development of cyclic peptide inhibitors of coagulation factor XIa for safer anticoagulation

Vanessa Carle

Hemostasis is a complex physiological process responsible for the prevention of blood loss caused by vascular injury. The dysregulation of this delicate mechanism can lead to thromboembolic diseases, the leading cause of death worldwide. Anticoagulants are ...

From Patients to Platelets and Back Again: Pharmacological Approaches to Glycoprotein VI, a Thrilling Antithrombotic Target with Minor Bleeding Risks

Nikolaos Stergiopoulos, Augusto Martins Lima

Despite significant advances in the treatment of thrombogenic diseases, antiplatelet therapies are still associated with a high bleeding risk. Consequently, potential benefits of preventing thromboembolic events by pharmacological agents need to be balance ...

Periostin Limits Tumor Response to VEGFA Inhibition

Ioanna Keklikoglou, Michele De Palma, Ece Kadioglu, Axel Bellotti

Resistance to antiangiogenic drugs limits their applicability in cancer therapy. Here, we show that revascularization and progression of pancreatic neuroendocrine tumors (PNETs) under extended vascular-endothelial growth factor A (VEGFA) blockade are depen ...

Development of cyclic peptide inhibitors of coagulation factor XII and matrix metalloproteinase 2

Jonas Alfred Karl Wilbs

Peptides represent a promising molecular class for drug development. They combine several strengths of small molecules (e.g. efficient tissue diffusion, low immunogenicity and access to chemical synthesis) and key properties of biologics such as monoclonal ...
