Abstract: The present invention pertains to a method for culturing a cell population including pluripotent stem cells and differentiated cells derived from pluripotent stem cells at a temperature of 40.5° C. or higher and reducing the pluripotent stem cells included in the cell population. The present invention also pertains to a method for reducing pluripotent stem cells from a cell population including pluripotent stem cells and differentiated cells derived from pluripotent stem cells, wherein the method includes a step for activating the TRPV-1 expressed in the pluripotent stem cells included in the cell population. The present invention makes it possible to reduce the pluripotent stem cells remaining in an undifferentiated state when inducing the differentiation of a pluripotent stem cell population.

Abstract: Provided is a LYPD1 inhibitor for promoting vascular endothelial network formation in a biological tissue. Also provided is a medicinal composition, said medicinal composition comprising a LYPD1 inhibitor as an active ingredient, for treating and/or preventing neoangiogenic disorders. Also provided is a method which comprises: (a1) a step for providing a cell population containing first cells expressing LYPD1 and vascular endothelial cells; (a2) a step for treating the cell population obtained in step (a1) with a LYPD1 inhibitor; and (a3) a step for culturing the cell population obtained in step (a2).

Abstract: Disclosed herein is a cell culture apparatus that can achieve appropriate culture conditions. The cell culture apparatus (1) includes: a cylindrical culture vessel (10) that holds a culture liquid containing cells; a supporting column (20) that stands upright in a center of an inner surface of a bottom (12) in the culture vessel; and a stirring device (30) that includes an attaching portion (32) that is attached to an upper portion of the supporting column so as to be rotatable relative to the supporting column and a stirring blade (34) whose upper portion is fixed to the attaching portion so as to rotate around the supporting column.

Abstract: A cell culturing device includes a culture tank, a shaft member at least partially disposed in the culture tank, a stirring mechanism supported by the shaft member, disposed in the culture tank, and a filter disposed in contact with the shaft member so as to suck the culture solution from the culture tank and/or to supply the culture solution to the culture tank. The shaft member is at least partially hollow, has openings to introduce the culture solution to the interior or to discharge the culture solution from the interior, and is unrotatable. Suction of the culture solution from the culture tank and/or supply of the culture solution to the tank is performed through the filter and the interior of the shaft member.

Abstract: The direct current vibration motor comprises a stator, a rotor rotatably attached on this stator, and a cylindrical cover for sealing the rotor. The stator has four permanent magnets arranged in a ring-like configuration and magnetized in an axial direction. The rotor is provided with an armature eccentrically fixed to a portion in the circumferential direction of the rotation shaft. The armature comprises a first coil and a second coil. Furthermore, the armature is provided with a pin formed of a magnetic body for regulating the static position so that the first coil and the second coil are fixed at a position where the first coil and the second coil are deviated from the central position of the magnetic pole of the stator. Current is supplied to the coils with the commutator and the brushes arranged with the spatial phase angle of 90°.
