  • Publication number: 20140162351
    Abstract: An operating efficiency of an observer is considerably restricted since it is not known at which position a culturing cell is disposed among a great number of pieces of holes of a culturing sheet. The culturing sheet is configured by a partitioning wall, a hole isolated by the partitioning wall, a local culturing region formed with plural local culturing region pillars a height of which is lower than that of the partitioning wall at a portion of a bottom face, and identification mark pillars formed at an identification mark region which differs from the culturing region at the bottom face of the hole. An identification mark is prevented from being unable to be optically recognized by adhering a spheroid to the identification mark region by making a diameter and a height of the identification mark pillar smaller than a diameter and a height of the local culturing pillar.

  • Publication number: 20130323839
    Abstract: Provided is a culture sheet which enables a technique for forming a three-dimensional tissue having uniform diameter without applying any chemical on the surface of a culture substrate. On the culture sheet (150) of the culture substrate, a plurality of holes (152) are formed and nanopillars (153), which are capable of controlling the adhesiveness and migration ability of cells, are formed on the bottom surface of each hole (152), said bottom face serving as a culture surface. The culture surface of each hole (151) is provided with a partition wall (152) and the internal nanopillars (153) are formed in the vicinity of the center of the hole (151). Owing to this configuration, the interaction among the disseminated cells can be restricted so that uniformly sized three-dimensional structures of the cells can be formed.

  • Patent number: 8530237
    Abstract: Provided are a technique for easily forming a spheroid by three-dimensionally culturing hepatocytes, and a technique for forming a spheroid having a higher expression level of a transporter MRP2 playing a role of biliary excretion than that of a conventional method. In order to solve the above-described problems, the present inventors have found out a condition under which hepatocytes easily form the spheroid on a nanopillar sheet. More specifically, this is related to a concentration of Type I collagen coated onto the NP sheet. Also, they have found out a condition under which an expression level of a gene related to the excretion of the formed spheroid is improved. More specifically, after the spheroid is previously formed, a biological matrix is overlayered thereon.

  • Publication number: 20120094922
    Abstract: The present invention relates to an action between an inhibitor of apoptosis (IAP) protein and members of the caspase family of cell death proteases, for example, an interaction of the X chromosome linked IAP (XIAP) and caspase-3, caspase-7 or caspase-9, wherein the IAP regulates the activity of the caspases. The invention provides screening assays for identifying agents that alter the specific association of an IAP such as XIAP, c-IAP-1 or c-IAP-2 and a caspase such as caspase-3 or caspase-7 or a pro-caspase such as pro-caspase-9, or that modulate the activity of a caspase in the presence of an IAP and that regulate the activation of a pro-caspase by an IAP. The invention further provides methods of reducing the severity of a pathologic condition in an individual by administering to the individual an agent that alters the caspase inhibitory activity of an IAP.
