  • Publication number: 20150140661
    Abstract: The method for producing a pancreatic hormone-producing cell according to the present invention is characterized in that a specific differentiation/induction promoter is added to a culture medium in the process of differentiating/inducing of a pluripotent stem cell or a pancreatic tissue stem/progenitor cell into the pancreatic hormone-producing cell. The differentiation/induction promoter to be used is: a polypeptide which comprises an amino acid sequence encoded by DNA comprising the nucleotide sequence represented by SEQ ID NO: 1 or a variant thereof; or a culture supernatant of a cell into which DNA comprising the nucleotide sequence represented by SEQ ID NO: 1 or DNA capable of hybridizing with DNA comprising a nucleotide sequence complementary to the aforementioned DNA under stringent conditions is integrated as a foreign gene.

  • Patent number: 8017320
    Abstract: Metastatic cancer cells originating from gastric cancer are detected by a method comprising the step of collecting a biological sample from a subject, the step of detecting the presence of at least either aldehyde dehydrogenase or dopa decarboxylase in the biological sample of the subject, and the step of determining that the possibility of containing metastatic cancer cells originating from the gastric cancer in the sample is high when at least either aldehyde dehydrogenase or dopa decarboxylase is present. By the use of these as markers for metastatic cancer cells originating from gastric cancer, the presence or absence of peritoneal metastasis in a gastric cancer patient can be detected rapidly and reliably, and data important for deciding whether intraperitoneal cancer chemotherapy should be applied is provided.
