<P>PROBLEM TO BE SOLVED: To provide an artificial tissue capable of transporting the nutrition necessary for maintaining the activity of the cells or tissues. <P>SOLUTION: To achieve the object, the present invention provides an artificial tissue including a blood vessel-containing tissue layer having at least two adjacent blood vessels and a cell disposed between the blood vessels, characterized in that an interval between the two adjacent blood vessels in the blood vessel-containing tissue layer is formed by a nutrition supplyable distance which does not cause a necrosis of the cell, and the blood vessel-containing tissue layer is formed on a vascular cell culture substrate, and the vascular cell culture substrate has flexibility of stretching the distance between the blood vessels to a distance capable of preventing adhesion, deformation or the like of blood vessels and shortening the distance to the nutrition supplyable distance. <P>COPYRIGHT: (C)2010,JPO&INPIT |
