Medical instrument includes a substrate, in which cells are in contact with or held on a surface of the substrate, and at least the surface of the substrate which holds the cells is formed of a fluorine-containing cyclic olefin polymer which contains a repeating structure unit represented by Formula (1), wherein in Formula (1), at least one of Rto Ris fluorine, an alkyl with 1 to 10 carbon atoms which contains fluorine, an alkoxy with 1 to 10 carbon atoms which contains fluorine, or an alkoxyalkyl with 2 to 10 carbon atoms which contains fluorine, Rto Rare selected from hydrogen and certain non-fluorinated groups when Rto Rdo not contain fluorine, Rto Rmay be the same as or different from each other, and Rto Rmay be bonded to each other to form a cyclic structure.

Medical instrument, cell culture method, fluorine-containing cyclic olefin polymer and fluorine-containing cyclic olefin polymer composition for it, and cultured cells

A culture material including a 4-methyl-1-pentene polymer for cells, tissues, or organs, the culture material having a water contact angle at a culture surface of 50&#xb0; to 100&#xb0;, a sagging distance by a test method described below of 0 to 5 mm, and an oxygen permeation rate at a temperature of 23&#xb0; C. and a humidity of 0% of 4500 to 90000 cm/(m&#xd7;24 h&#xd7;atm). A test piece having the same material as the culture material and the same thickness as the culture surface of the culture material and having a flat plate shape of 100 mm long and 10 mm wide is made. The test piece is fixed onto a test board in a state where the test piece protrudes lengthwise in a horizontal direction from a top surface of the test board, the top surface being horizontal.

Culture material and use thereof

The purpose of the present invention is to provide a medical film having excellent transparency, heat resistance, and solvent resistance. This medical film is a medical film including a heat-resistant resin having a glass transition temperature measured by thermomechanical analysis TMA of 190&#xb0; C. or higher wherein the medical film has a total light transmittance of 80% or higher at a thickness of 10 &#x3bc;m and a b* value in the L*a*b* color system of 10 or lower.
