The high heterogeneity of hepatocellular carcinomas (HCCs) complicates stratification of HCC patients for treatment. Therefore, it is necessary to establish a comprehensive panel of HCC biomarkers related to tumour behaviour and cancer prognosis. Resected HCCs from 251 patients were stained for hepatic progenitor cell (HPC) markers epithelial cell adhesion molecule (EpCAM), neural cell adhesion molecule (NCAM), delta-like 1 homolog (DLK1), and cytokeratin 19 (CK19). Staining patterns were analysed for their prognostic association with relapse-free survival and overall survival...

Mulberry (Morus alba) has been used in traditional oriental medicine since ages. Recently, it has been reported that mulberry produces hypotensive effects through the eNOS signaling pathway. However, the mechanism underlying the hypotensive effects of mulberry is not entirely clear. Moreover, the effects of mulberry on vascular remodeling events such as hyperplasia, an important etiology in the pathogenesis of hypertension and arteriosclerosis, are also ambiguous. Here, we hypothesized that an ethanolic extract of mulberry fruit (EMF) has beneficial effects on vascular remodeling and produces hypotensive effects...

High donor variation makes comparison studies between different dental sources dubious. Dental tissues offer a rare opportunity for comparing the biological characteristics of haploidentical mesenchymal stem cells (MSCs) isolated from the same donor. The objective was to identify the optimal dental source of MSCs through a biological and functional comparison of haploidentical MSCs from gingival (GMSCs) and dental pulp stem cells (DPSCs) focusing mainly on their angiogenic potential. The comparison study included (1) surface markers expression, (2) mesodermal differentiation capacity (chondrogenic, adipogenic, and osteogenic), (3) proliferation, (4) migration potential, (5) ability to form colony units, and (6) angiogenic potential in vitro and in vivo...

Right heart catheterization is commonly used to measure right ventricle hemodynamic parameters and is the gold standard for pulmonary arterial hypertension diagnosis; however, it is not suitable for patients' long-term follow-up. Non-invasive echocardiography and nuclear medicine have been applied to measure right ventricle anatomy and function, but the guidelines for the usefulness of clinical parameters remain to be established. The goal of this study is to identify reliable clinical parameters of right ventricle function in pulmonary arterial hypertension patients and analyze the relationship of these clinical parameters with the disease severity of pulmonary arterial hypertension...

Investigating the complex interplay between blood cells and the endothelium is crucial in understanding the pathophysiology of many diseases. Observation of the in vivo vasculature is difficult due to the complexities of vessel geometry, limited visualization capability, as well as variability and complexity inherent to biologic systems. Therefore, in vitro systems serve as ideal tools to study these cellular interactions. Microfluidic technologies are an ideal tool for recapitulating the vasculature in vivo as they can be used to fabricate fluidic channels on the size scale capillaries using gas permeable, biologically inert, and optically transparent substrates...

Magnetic particle imaging (MPI) is an emerging ionizing radiation-free biomedical tracer imaging technique that directly images the intense magnetization of superparamagnetic iron oxide nanoparticles (SPIOs). MPI offers ideal image contrast because MPI shows zero signal from background tissues. Moreover, there is zero attenuation of the signal with depth in tissue, allowing for imaging deep inside the body quantitatively at any location. Recent work has demonstrated the potential of MPI for robust, sensitive vascular imaging and cell tracking with high contrast and dose-limited sensitivity comparable to nuclear medicine...

Auxetic scaffolds, i.e. scaffolds that can display negative Poisson's ratio, have unique physical properties and can expand transversally when axially strained or contract under compression. Auxetic materials have been used for bioprostheses and artery stents due to the enhanced compressive strength and shear stiffness. In vascular tissue engineering, auxetic scaffolds allow the widening of blood vessels when blood flows through (creating compressive stress) to prevent the blockage. However, the influence of auxetic materials on the cellular fate decision in local environment is unclear...

Stroke and myocardial infarction are among the most common causes of mortality and disability in the world. The ischemic injury underlying these illnesses is complex, involving intricate interplays among many biological functions including energy metabolism, vascular regulation, hemodynamics, oxidative stress, inflammation, platelet activation, and tissue repair that take place in a context- and time-dependent manner. The current drug therapy of choice is to timely resupply the blood to the ischemic tissue; but reperfusion may introduce additional harm to the tissue through a process known as ischemia/reperfusion injury...
