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 ...
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.
