A team of researchers at UC Davis has succeeded in growing capillaries on and into a neural organoid. In their paper published in the journal NeuroReport, the group describes how they grew capillaries with the organoid and ...
More than 40 billion capillaries—tiny, hair-like blood vessels—are tasked with carrying oxygen and nutrients to the far reaches of the human body. But despite their sheer number and monumental importance to basic functions ...

(Medical Xpress)—The blood-brain barrier (BBB) prevents most large or hydrophilic (polar) molecules from getting into the brain. For many neurological diseases, like Parkinson's, the presence of the BBB severely limits ...
Capillaries ( /ˈkæpɨlɛri/) are the smallest of a body's blood vessels and are parts of the microcirculation. They are only 1 cell thick. These microvessels, measuring 5-10 μm in diameter, connect arterioles and venules, and enable the exchange of water, oxygen, carbon dioxide, and many other nutrient and waste chemical substances between blood and surrounding tissues. During embryological development, new capillaries are formed by vasculogenesis, the process of blood vessel formation occurring by a de novo production of endothelial cells and their formation into vascular tubes. The term angiogenesis denotes the formation of new capillaries from pre-existing blood vessels.
