    摘要: Described herein are engineered multilayered vascular tubes comprising at least one layer of differentiated adult fibroblasts, at least one layer of differentiated adult smooth muscle cells, wherein any layer further comprises differentiated adult endothelial cells, wherein said tubes have the following features: (a) a ratio of endothelial cells to smooth muscle cells of about 1 : 99 to about 45:55; (b) the tube is compliant; (c) the internal diameter of the tube is about 6 mm or smaller; (d) the length of the tube is up to about 30 cm; and (e) the thickness of the tube is substantially uniform along a region of the tube; provided that the engineered multilayered vascular tube is free of any pre-formed scaffold. Also described herein are methods of forming said tubes and uses for said tubes including methods for treating patients, comprising providing such a tube into to a patient in need thereof.
