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 is disclosed for cryopreservation of cardiocytes derived from pluripotent stem cells or mesenchymal stem cells derived from adipose tissue or bone marrow, the method maintaining the function of the cardiocytes derived from differentiated pluripotent stem cells or mesenchymal stem cells derived from adipose tissue or bone marrow, and yet reducing the possibility for tumorigenesis of undifferentiated pluripotent stem cells or mesenchymal stem cells derived from adipose tissue or bone marrow. A method is also disclosed for cryopreservation of cardiocytes derived from pluripotent stem cells or mesenchymal stem cells (derived from adipose tissue or bone marrow, the method including dissociating cells from a cell population which has been induced to differentiate into cardiocytes from pluripotent stem cells or mesenchymal stem cells derived from adipose tissue or bone marrow.

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.
