Instead of dispensing ink, Organovo's bioprinter uses two robotic tips to deposit globs of cells — in this case, endothelial cells that line blood - vessel walls, smooth muscle cells that regulate vessel dilation and contraction, and structural fibroblast cells.

In a series of studies this year, molecular geneticists at the University of Pittsburgh School of Medicine used a harmless virus to ferry new genes through the bloodstream, across blood vessel walls, and into almost every muscle cell in the bodies of hamsters bred to have human genetic diseases.

A specific lung - targeting molecule is attached to the carrier's surface and the steriod, dexamethasone, an anti-inflammatory, is loaded into the nanogel, which then binds to lung endothelial cells lining the inside wall of the blood vessels where it rapidly delivers the drug.

Researchers at Hokkaido University in Japan have demonstrated that a molecule, called biglycan, plays an intrinsic role in attracting tumour cells toward the inner wall of tumour blood vessels.

When cancer cells interact with the walls of the blood vessels, EPHA2 is activated and the tumour cells remain inside the blood vessels.

By softening their bulky nuclei and pushing them to the front edge of their cells, white blood cells probe apart scaffolding in the blood vessel walls and squeeze through, researchers report online today in Cell Reports.

In this study, NIH scientists used mouse models to show that anthrax toxin proteins work by specifically targeting the cells that line the inner walls of the blood vessels feeding the tumor.

KLF4: Selectively lowering levels of klf4 in smooth muscle cells in blood vessel walls causes beneficial changes in the behavior of these cells.

Recent publications support the hypothesis that MSCs develop from the blood vessel wall and belong to a subset of perivascular cells (i.e., pericytes).

These abnormal cells — in the case of pulmonary hypertension, those that line the blood vessels leading to the lungs — release signals that stimulate the growth of small new blood vessels to feed the renegade cells, allowing further proliferation, and thickening of the vessel walls.

High sodium diets are commonly used to study diet induced hypertension, since increasing levels of circulating sodium cause cells to release water (due to osmotic pressure) which elevates the pressure on blood vessel walls.

His team applied, among others, techniques of confocal microscopy and cell sorting by flow cytometry which led to the discovery in human muscle biopsies that these myoendothelial cells are located adjacent to the walls of blood vessels.

The oils help relieve the itching and irritation of hemorrhoids, while the herbs treat the skin and the blood vessels through the cell walls.

AGEs not only age cells — they bind to the walls of blood vessels, causing them to stiffen.

It does an excellent job of widening the blood vessels by relaxing muscle cells in the vessel walls to regulate blood pressure.

Research has shown that curcumin promotes healthy function of the endothelium, the thin layer of cells that creates an interface between circulating blood and the vessel wall.

There are multiple factors that can cause inflammation and damage of the endothelium, the layer of cells that form the inside wall of every blood vessel in your body:

• widespread effects on circulation, muscles and sugar metabolism • raised heart rate • increased heart output • increased rate and depth of breathing • increased metabolic rate • increased force of muscular contraction • delayed muscular fatigue • reduced blood flow to bladder (muscular walls relax and sphincters contract) • reduced blood flow to intestines • increased blood pressure • increased sugar (glucose) in the blood • increased break - down of glucose for energy *, especially in muscle cells • increased free fatty acids in the blood * • more oxidation of fatty acids to produce energy * • more ATP (the cells» primary energy compound) produced * • blood vessels constrict

In addition to the niacin it supplies, brown rice may also help raise blood levels of nitric oxide, a small molecule known to improve blood vessel dilation and to inhibit oxidative (free radical) damage of cholesterol and the adhesion of white cells to the vascular wall (two important steps in the development of atherosclerotic plaques).

When the walls of blood vessels lose elasticity excess fluids and waste products, instead of being excreted, press towards the fat tissue where they attach to the fat cells, thus causing swelling and cellulite.

The only effective way of treating cellulite is addressing the above mentioned causes, focusing on strengthening the connective tissue (collagen) and muscles found under the skin, a long - term weight loss (burning fat slowly and systematically), slowing down the ageing process of the skin cells, improving blood circulation and strengthening blood vessel walls, detoxification of the body and liver, and improving overall health.
