  • Patent number: 8383409
    Abstract: The invention is directed to methods for the propagation or cultivation of cells including preparing a cell culture substrate, wherein the cell culture substrate includes a substrate and a layer formed by surface modification. The layer includes a polymer containing an amino group. The polymer is produced by reacting a polymer represented by formula (II): with a polymer having at least one amino group, —NH2, capable of forming a Schiff base in a monomer of formula (II), thereby forming a polymer layer constituting the layer formed by surface modification. “n” in Formula (II) is 0 or a positive integer, and m is a positive integer. n and m represent the degree of polymerization. Formula (II) is formed by chemical vapor deposition of formyl[2.2]paracyclophane. The methods further include providing cells in a medium; inoculating the cells onto the cell culture substrate; and culturing the cells, wherein the cells adhere to the cell culture substrate.

  • Publication number: 20110136234
    Abstract: A cell culture substrate which is durable and which can be readily produced in commercial scale at a low cost, and its production method are provided. The cell culture substrate comprises a substrate and a layer formed by surface modification, which comprises a polymer containing amino group produced by reacting a polymer represented by the following formula (II): (wherein n is 0 or a positive integer, and m is a positive integer, the n and m representing degree of polymerization) formed by chemical vapor deposition of formyl[2.2]paracyclophane represented by the following formula (I): (wherein k is 0 or 1) with a polymer having at least one amino group (—NH2) capable of forming Schiff base in its monomer. The production method of the cell culture substrate comprises the step of synthesizing such polymer on the substrate.
