Abstract: A heart failure diagnostic device includes a piezoelectric sensor sheet having flexibility and configured to output a detection signal corresponding to an input vibration. A respiratory signal acquisition unit is configured to extract, as a respiratory signal, a signal of a vibration frequency caused by respiration from the detection signal detected by the piezoelectric sensor sheet. A power spectrum calculator is configured to obtain a power spectrum of a respiratory frequency band from the respiratory signal, and a signal corrector is configured to correct the detection signal such that in the power spectrum, a maximum value of a first-order frequency component of a respiratory waveform is not smaller than 1.5 times a maximum value of a second-order frequency component of the respiratory waveform to obtain the respiratory signal.

Abstract: The present invention provides a method for preparing a clinically applicable, safe and less damaged cardiomyocyte population through a brief and simple procedure from a cell population obtained by induced differentiation of pluripotent stem cells into cardiomyocytes. The present invention relates to a method for preparing a cardiomyocyte population, the method comprising the steps of: (1) inducing pluripotent stem cells to differentiate into cardiomyocytes, (2) bringing a cell population obtained by the induced differentiation into contact with a laminin selected from the group consisting of laminin α2β1γ1, laminin α2β2γ1, laminin α1β1γ1 and laminin α1β2γ1, or a fragment thereof having integrin binding activity, and (3) retrieving cells adherent to the laminin or the laminin fragment.

Abstract: A method for treating a disease associated with tissue abnormality in a subject. The method includes administering an amount of a pharmaceutical composition to a subject in need of treating a disease associated with tissue abnormality, the pharmaceutical composition comprising a laminate comprising a fibrin gel and a cell culture. The laminate is produced by a method, which includes forming a fibrin gel layer on an upper surface of the cell culture by a reaction between fibrinogen and thrombin, wherein: the cell culture is prepared on a culture dish and the laminate of the fibrin gel and the cell culture are transferred onto a subject's heart. The laminate further includes a reinforcing portion made of a fibrin gel, the reinforcing portion formed by laminating the fibrin gel on the fibrin gel layer of the laminate of the cell culture and the fibrin gel.

Abstract: An object of the present invention is to provide a pericyte-like cell having high angiogenic potential with a higher cell proliferation ability than a primary pericyte available in the past and high VEGF expression, and a method for producing the same. Provided are a method for producing a VEGF-highly expressing pericyte-like cell, the method including selecting a CD56(−) pericyte-like cell from a population including a pericyte-like cell obtained by inducing differentiation of a pluripotent stem cell; and a VEGF-highly expressing pericyte-like cell produced by the production method.

Abstract: When detachment of a cell sheet from a culture dish has started at an unintended timing, immediately detach the cell sheet from the culture dish while preventing generation of wrinkles and the like in the cell sheet. A cell culture device captures an image of cells in the culture dish, and controls a cooling mechanism and a shaking mechanism based on the image so as to shake the cells while cooling them.
