  • Publication number: 20120214193
    Abstract: An object of the present invention is to provide a method for increasing the change in the fluorescent intensity as emitted from potential-sensitive fluorochromes depending on a potential or ionic strength change. Another object of the present invention is to measure the changes in the activity potentials of ES cell- or iPS cell-derived cardiomyocytes that have heretofore been impossible to measure. The present inventors screened a variety of substances and found that vitamin E has an action for increasing the sensitivity of potential-sensitive fluorochromes whereas cholesterol has an action for enhancing the fluorescent intensity of potential-sensitive fluorochromes. In addition, it has become clear that these substances can be combined in such a way that the sensitivity of a potential-sensitive fluorochrome is increased by vitamin E while at the same time its absolute fluorescent intensity is enhanced by cholesterol.

  • Publication number: 20120094383
    Abstract: The present invention has as its object developing a method that does not involve genomic modification and which yet is capable of inducing cell death in pluripotent stem cells such as embryonic stem cells and induced pluripotent stem cells, as well as in differentiated cells other than cardiomyocytes derived from pluripotent stem cells, but not in cardiomyocytes. It has been revealed that by establishing a method capable of inducing cell death in cells other than cardiomyocytes in a very efficient manner by adding a substance having no recognized inherent toxicity or cell death inducing action to the culture conditions for pluripotent stem cells and non-cardiomyocytes, the stated problem can be solved without relying upon genomic modification.

  • Publication number: 20110007762
    Abstract: To constitute an optical module in which a comb-shaped submount is fixed on a heat sink and a device having an optical functioning unit is mounted on the comb-shaped submount, a stress buffering block that relaxes a thermal stress acting between the heat sink and the comb-shaped submount is placed between the heat sink and the comb-shaped submount. With this configuration, a thermal stress acting between the comb-shaped submount and the device mounted thereon is relaxed, and as a result, long-term reliability of bonding parts between the comb-shaped submount and the device is enhanced.

  • Publication number: 20100189699
    Abstract: The object of the present invention is to improve the post-transplantation engraftment rate of cardiomyocytes that have been purified to such an extent that they are free from non-cardiomyocytes and any components derived from other species. To solve this problem, the present inventors studied the possibility of constructing cell masses from the purified cardiomyocytes. As a result, they revealed that the stated problem could be solved by providing a method of preparing cell masses of cardiomyocytes derived from pluripotent stem cells, characterized in that cell masses of aggregated cells containing cardiomyocytes that had been differentiated and induced from pluripotent stem cells were dispersed to single cells to thereby obtain purified cardiomyocytes, which were then cultured in a culture medium under serum-free conditions so that they were reaggregated.

  • Publication number: 20100145441
    Abstract: An objective of the present invention is to analyze the function of anti-angiogenic factors in cardiac valves or such to elucidate the developmental mechanism of angiogenesis-induced diseases. A more specific objective is to provide therapeutic agents for angiogenesis-induced diseases such as valvular heart disease, and methods of efficiently screening for the therapeutic agents. The present inventors discovered that chondromodulin-I was markedly expressed in cardiac valves, and plays an important role in maintaining normal functions of the valves by preventing angiogenesis, thickening, and calcification which lead to valvular heart diseases. Chondromodulin-I proteins and substances that activate the expression or function of the proteins are expected to have therapeutic effects against angiogenesis-induced diseases.

  • Publication number: 20090242548
    Abstract: The present invention relates to a tape heater including: at least one flexible fabric base formed from a heat-resistant thread, the at least one flexible fabric base including a first fabric base part and a second fabric base part; and a heater member, in which the heater member is interposed between the first fabric base part and the second fabric base pan. Since the heater member is interposed between the fabric base(s), the tape heater of the present invention exhibits superior flexibility and stretchability and is superior in easily being wrapped around a pipe, as well as reliably protecting the heater member. Further, tape heaters can be continually manufactured, so long as weaving or knitting of the fabric base(s) is caused to proceed while the heater member is interposed between the fabric base(s), to thus join the fabric base(s). Hence, enhancement of production efficiency and prevention of an increase in production cost can be attained.
