    • In a process for producing tubular shaped fibrous articles of small diameter by heating and cooling a fibrous bundle containing at least 20 weight % of hot-melt-adhesive composite fibers, the improvements comprise using a shaping apparatus including an injecting chamber, an injecting hole formed in the wall of the chamber, a fibrous bundle outlet provided with a nozzle of a desired shape in cross-section, a cylindrical pipe for introducing the fibrous bundle, which has a cross-sectional area larger than that of the outlet, is located at a position opposite to the outlet and projects toward the outlet and terminates in the injecting chamber, and a core pipe which is open at its base on the outside of the injecting chamber, has its one end inserted through the cylindrical pipe and extending into the nozzle through the injecting chamber, and having a vent in its portion exposed within the injecting chamber, and passing the fibrous bundle through the cylindrical pipe to the outlet, while injecting a hot compressed gas through the injecting hole, thereby to heat and shape the fibrous bundle to and at its hot-melt-adhesive temperature.

    • 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.
    • 提供通过三维培养肝细胞容易地形成球状体的技术,以及形成具有比常规方法具有胆汁排泄作用的转运蛋白MRP2更高表达水平的球状体的技术。 为了解决上述问题,本发明人发现肝细胞容易在纳米柱片材上形成球状体的条件。 更具体地说,这涉及涂覆在NP片上的I型胶原蛋白的浓度。 此外,他们发现了与形成的球体的排泄相关的基因的表达水平提高的条件。 更具体地说,在预先形成球体之后,将生物体叠加在其上。
