  • Method of producing three-dimensional tissue and method of producing extracellular matrix used in the same
    Patent number: 8137964
    Abstract: The present invention provides a novel method of producing a three-dimensional tissue by which cell lamination can be carried out easily. According to the method, a three-dimensional tissue in which cell layers are laminated with an extracellular matrix intervening between each pair of the adjacent cell layers is produced by: (A) forming a cell layer on a substrate; (B) bringing the cell layer formed on the substrate into contact with a solution containing a first substance and a solution containing a second substance alternately, thus forming, on the cell layer, an extracellular matrix in which the first substance and the second substance are laminated alternately; and (C) culturing a cell on the extracellular matrix to form a further cell layer.

  • Twist drill
    Patent number: 4756650
    Abstract: A twist drill including a body characterized by the outer portion of each of the heels bulging toward the main flute as compared with that of the standard twist drill, the main lips each bulging in a triangular shape in cross section toward the main flute as compared with that of the standard twist drill, and a subflute having a substantially U-shaped cross section and axially formed in the inner portion adjacent to the axis of the twist drill of each of the heels along the main flute for a predetermined distance from the tip.
