Abstract: A method of producing a three-dimensional cell structure includes producing a mixture of a cell cluster including an endothelial cell, an extracellular matrix component, and a polymer electrolyte, removing a liquid from the mixture to obtain a cell aggregate, and culturing the cell aggregate in a medium to obtain a three-dimensional cell structure with a thickness greater than 150 μm and having a vascular network. The extracellular matrix component is collagen or a collagen analog, and the polymer electrolyte is heparin or a heparin analog having a final concentration of 0.001 mg/mL or higher in the mixture.

Abstract: A detection method including bringing liquid including a target nucleic acid into contact with a well array having wells such that at most one molecule of the target nucleic acid is included per well, sealing the well such that the target nucleic acid remains in the well, amplifying, in the well, a signal derived from the target nucleic acid, detecting the signal emitted from the well, and detecting whether the target nucleic acid includes at least one of a first nucleic acid, a second nucleic acid, and a double-stranded nucleic acid resulting from complementary binding of the first and second nucleic acids. The signal includes at least one of a first signal emitted by binding of a first specific binding substance to the first nucleic acid, and a second signal different from the first signal and emitted by binding of a second specific binding substance to the second nucleic acid.

Abstract: A decorative sheet comprises a substrate layer; a pattern layer provided on the first front surface of the substrate layer; and a thermoplastic resin layer provided on the second front surface of the pattern layer. A test piece of 8 mm width from the decorative sheet is taken; the storage modulus is measured with an initial chuck distance of 10.77 mm, a start temperature of 30° C., an end temperature of 150° C., a temperature increase rate of 5° C./min, and a measurement frequency of 1.0 Hz. The ratio of the difference between the second storage modulus and a third storage modulus when the decorative sheet changes from the transition region to a rubbery flat region to the difference between a first storage modulus when the environmental temperature is 30° C. and a second storage modulus when the decorative sheet changes from a glassy region to a transition region is 3.5 or less.
