摘要： 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.

摘要： 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.
摘要翻译： 观察者的操作效率受到相当的限制，因为在培养板的大量孔中不设置培养单元的位置。 培养片由分隔壁，由分隔壁隔离的空穴构成，局部培养区形成有多个局部培养区柱，其高度低于底面部分的分隔壁， 识别标记柱形成在与孔底面的培养区域不同的识别标记区域。 通过使识别标记柱的直径和高度小于局部培养柱的直径和高度，通过将球体粘附到识别标记区域来防止识别标记不被光学识别。

摘要： 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.

摘要： The present invention provides a monoclonal antibody displaying excellent specificity against heparan sulfate saccharide chains for the analysis of heparan sulfate saccharide chains specific to dentin. The invention also provides a method of evaluating reproductive dentin using the monoclonal antibody. The anti-heparan sulfate monoclonal antibody reacts against dentin-derived heparan sulfate and in particular the anti-heparan sulfate monoclonal antibody reacts strongly and specifically with uncalcified predentin regions. In the method of evaluating dentin, the antibody is reacted against an isolated dentin-derived sample and the reaction is used in order to evaluate the development of dentin.
