  • Patent number: 8735152
    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.

  • Patent number: 8709816
    Abstract: The present invention relates to a method for diagnosing, and treating renal disease in a patient by having a test performed for detecting or quantifying one or more renal disease markers present in a test blood sample from the patient; and administering treatment to improve renal function. In particular embodiments, the test performed quantifies cis-aconitate, and the patient is identified as having the renal disease when a concentration of cis-aconitate present in the patient's test blood sample is higher than that of a control. Methods of the present invention can allow diagnosis and treatment of patients with early stage renal disease, such as early stage renal failure. Another aspect of the present invention relates to methods for screening for a prophylactic/therapeutic agent for treating renal disease using one or more renal disease markers.
