    • It is an objective of this invention to provide a cardiomyocyte culture support used for obtaining cardiomyocytes having a controlled orientation of beating that are thus available for myocardial regenerative therapy, and to provide a method for producing the same.The present invention provides a cardiomyocyte culture support having a cured polymerizable liquid crystal layer having a molecular oriented surface. In addition, the present invention provides a method for producing a cardiomyocyte culture support, such method comprising the steps of: applying a coating solution comprising a polymerizable liquid crystal on a base material having orientation ability so as to form a coating film; allowing the polymerizable liquid crystal comprised in the coating film to be oriented so as to be in a liquid crystal phase state; and forming a cured polymerizable liquid crystal layer by irradiating the coating film with ionizing radiation or ultraviolet rays so as to cure the polymerizable liquid crystal in a liquid crystal phase state by polymerization.

    • An object of the present invention is to provide a cell culture support making the detachment of a cell sheet easy as well as enabling the formation of a uniform cell sheet. The present invention relates to a method for manufacturing a cell culture support having a temperature responsive polymer immobilized onto the surface thereof via covalent bonding, the method including a coating step in which a composition including a monomer that can form the polymer by polymerization by radiation irradiation, an organic solvent and, in some cases, a prepolymer formed by polymerization of the monomer is coated onto the substrate having a surface containing a material which can be covalently bonded to the temperature responsive polymer by radiation irradiation to form a film on the surface of the substrate, a radiation irradiation step in which a polymerization reaction and a binding reaction between the substrate surface and the temperature responsive polymer are allowed to proceed by irradiating radiation to the film, and a drying step to dry the film.
    • 本发明的目的是提供使细胞片分离容易以及能够形成均匀的细胞片的细胞培养支持体。 本发明涉及通过共价键固定在其表面上的具有温度响应性聚合物的细胞培养支持体的制造方法,该方法包括以下步骤:包括可以通过辐射聚合聚合形成聚合物的单体的组合物 有机溶剂,在一些情况下,通过单体聚合形成的预聚物被涂覆到具有包含可通过辐射照射共价键合到温度响应性聚合物的材料的表面的基材上,以在表面上形成膜 通过照射辐射使膜进行聚合反应和基板表面与温度响应型聚合物之间的结合反应的放射线照射步骤,以及干燥步骤。
