Abstract: The object of the present invention is to find a pharmaceutical having strong cancer therapeutic effect. The present invention provides a pharmaceutical composition for cancer therapy comprising a transcription or processing product of a gene encoding a miRNA, wherein said miRNA is one or more miRNAs selected from the group consisting of miR-3140, miR-137, miR-631, and miR-657, pharmaceutical composition.

Abstract: A cell tracking method for performing cell tracking on the basis of a plurality of cell images captured in time series, including an extraction process of extracting a tracking region corresponding to the cell for each cell images; a tracking process of calculating a change information in a position of the extracted tracking region and tracking the cell on the basis of the change information; a determination process of determining whether or not the cell as a tracking target is in a cell division state on the basis of the cell image; and an analysis process of analyzing a movement state of the cell on the basis of the change information from which the change information in a period of the cell division state is excluded when the cell is determined to be in the cell division state in the determination process.

Abstract: An aim of the present invention is to provide a method for culturing a human pluripotent stem cell while maintaining an undifferentiated state, more efficiently than conventional methods, and a kit therefor. The pluripotency of a stem cell was found to be maintained at a high rate, regardless of experimenter's proficiency in culturing techniques, by (a) culturing a human pluripotent stem cell in a first medium which a medium for pluripotent stem cell comprising activin; (b) replacing the first medium with a second medium which is a medium for pluripotent stem cell comprising no activin, and culturing the human pluripotent stem cell, (c) subculturing the human pluripotent stem cell into the first medium, and then repeating the above (b) and (c) sequentially.
