Mature and progenitor endothelial cells perform angiogenesis also under protease inhibition: the amoeboid angiogenesis

Journal of Experimental & Clinical Cancer Research, 2018
Background Controlling vascular growth is a challenging aim for the inhibition of tumor growth and metastasis. The amoeboid and mesenchymal types of invasiveness are two modes of migration interchangeable in cancer cells: the Rac-dependent mesenchymal ...

Hybrid Biofabrication of a Hierarchically Organized Periosteum‐Inspired In Vitro Platform

Advanced Healthcare Materials, EarlyView.
A hybrid biofabrication strategy integrates melt electrowriting with extrusion‐based 3D bioprinting to create a hierarchically organized periosteum‐inspired in vitro platform. Spatially defined osteogenic, fibrous, and endothelial cell‐containing compartments support long‐term culture, osteogenic maturation, and CD31+ endothelial cell organization ...

Assessment of Tumor Vascularization: Immunohistochemical and Non-Invasive Methods

The International Journal of Biological Markers, 1999
Growth of solid tumors beyond a certain mass is dependent on the vascular bed from pre-existing host vasculature. The process of angiogenesis is essential not only for primary tumor growth but also for metastasis.

Lipid Signaling in Ocular Neovascularization

, 2020
Vasculogenesis and angiogenesis play a crucial role in embryonic development. Pathological neovascularization in ocular tissues can lead to vision-threatening vascular diseases, including proliferative diabetic retinopathy, retinal vein occlusion ...

A Retinal Matrix Stiffening Model Reveals FAK‐Dependent Mechanotransduction in Pericytes Underlies Vascular Destabilization

Advanced Materials, EarlyView.
In this study, we show that retinal matrix stiffness is increased in diabetic mice. Using engineered human vascular models with controlled matrix stiffness, we demonstrate that stiffening activates focal adhesion kinase (FAK) signaling in pericytes, suppresses Notch signaling, and disrupts vascular morphology.

Formação in vitro de túbulos capilares a partir de células de sangue de cordão umbilical humano com perspectivas para aplicação terapêutica In vitro formation of capillary tubules from human umbilical cord blood cells with perspectives for therapeutic application

Brazilian Journal of Cardiovascular Surgery, 2008
OBJETIVO: As células progenitoras endoteliais (CPE), caracterizadas pelo marcador CD133+, contribuem para a neovascularização, e o aumento no número dessas células pode ser uma ferramenta terapêutica promissora. O sangue de cordão umbilical humano contém

Pre‐Regenerative Endothelial Cells Empowered by Antler Blood Exosomes Orchestrate Peripheral Nerve Repair

Advanced Science, EarlyView.
The pre‐regenerative vascular niche (PVN) is essential for nerve repair, yet its endothelial blueprint remains unclear. We identified angiogenic ECs (AECs) as the dominant pre‐regenerative subset and found that antler blood–derived exosomes (AB‐EXO) promote repair via IMP3.

Engineering Microbial Particles for Next‐Generation Biomedical Platforms

Advanced Science, EarlyView.
Microbe‐derived particles (MDPs), which include extracellular vesicles, outer membrane vesicles, inclusion bodies, polysaccharide particles, and virus‐like particles, represent a rapidly expanding category of bioinspired nanomaterials. With their natural origin, intrinsic biocompatibility, and highly programmable functionality, MDPs serve as a ...
