Abstract: The present invention relates to directed differentiation and maturation of hepatocyte-like cells. In particular, the present invention relates to exposure of hepatocyte-like cells to an activator of a retinoic acid responsive receptor, such as retinoic acid (RA), optionally in combination with an inhibitor of GSK-3 (Glycogen synthase kinase 3) or activator of Wnt signalling and/or with the overlay of the cells with one or more components characteristic of the mammalian extracellular matrix (matrix overlay). The present invention also relates to exposure of hepatocyte-like cells to an activator of a retinoic acid responsive receptor, such as retinoic acid (RA), optionally in combination with an inhibitor of a cycline dependent kinase (CDK) and/or with the overlay of the cells with one or more components characteristic of the mammalian extracellular matrix (matrix overlay).

Abstract: A balloon includes two joined plastic films. The balloon includes: a gas supply valve sandwiched between and joined to the first film and the second film; a first chamber receiving air supplied from the gas supply valve for expansion; and a second chamber communicating to the first chamber. The gas supply valve includes a gas passage that extends from a gas inlet positioned on an outer side of the second chamber to an inside of the first chamber through the second chamber. Part of the first film and the second film between the first chamber and the second chamber and between the gas passage and a peripheral edge of the balloon are joined together to form a first weld portion and a second weld portion. The first weld portion is formed on an opposite side of the second weld portion with the gas passage sandwiched therebetween.

Abstract: A method of producing pancreatic cells or pancreatic cell precursors expressing at least 5% PDX1/NKX6.1 double positive, comprising exposing definitive endoderm cells to an effective amount of one or more small molecules, to differentiate the human definitive endoderm cells into the pancreatic cells or pancreatic cell precursors. The present invention also relates to pancreatic endoderm cells produced by said methods and uses of said pancreatic endoderm cells.
Abstract: A method for quantification of an adeno-associated virus genome, including the steps of (a) preparing a composition containing a sample, at least one primer pair for use in amplification of only a nucleotide sequence contained in inverted terminal repeats of an adeno-associated virus, and an intercalating dye; (b) performing nucleic acid amplification reaction using the composition prepared in the step (a); and (c) detecting an amplified product obtained in the step (b). The present invention is especially useful in the fields of medicine, gene engineering, and biology.
Abstract: The present invention is directed to methods to prepare a DNA molecule or a plurality of DNA molecules by random fragmentation. In some embodiments, the present invention regards preparing a template for DNA sequencing by random fragmentation. In specific embodiments, the random fragmentation comprises chemical fragmentation, mechanical fragmentation, or enzymatic fragmentation. In further specific embodiments, a universal sequence is attached to the 3? end of the DNA fragments, such as by ligation of an adaptor sequence or by homopolymeric tailing with terminal deoxynucleotidyltransferase. In other embodiments, a library is prepared with methods of the present invention.

Abstract: The present invention relates to a fusion polypeptide containing, in a direction of from an N-terminal side to a C-terminal side, one or more peptides which bind to a PCNA, and a polypeptide having a DNA polymerase activity; a method for amplifying nucleic acids using the polypeptide; and a composition and a kit, containing the polypeptide. According to the present invention, it is made possible to amplify a long-strand DNA in a short time in amplifying nucleic acids in the presence of PCNA even with a Pol I-type DNA polymerase.

Abstract: The present invention concerns preparation of DNA molecules, such as a library, using a stem-loop oligonucleotide. In particular embodiments, the invention employs a single reaction mixture and conditions. In particular, at least part of the inverted palindrome is removed during the preparation of the molecules to facilitate amplification of the molecules. Thus, in specific embodiments, the DNA molecules are suitable for amplification and are not hindered by the presence of the palindrome.

Abstract: The present invention relates to the directed differentiation of mammalian pluripotent stem cells, especially human pluripotent stem (hPS) cells, into endodermal cells. In particular, the present invention relates to the treatment of mammalian pluripotent stem cells, especially hPS cells, with a DNA demethylating agent while undergoing differentiation into endodermal. The inventors have, as disclosed herein, found that exposing differentiating mammalian pluripotent stem cells, especially hPS cells, to a DNA demethylating agent leads to an improved morphology and improved yield of endodermal cells. The treatment with a DNA de-methylating agent also leads to a significant down-regulation of expression of the stem cell marker Oct4 and to an improved expression of endoderm specific markers, notably sox17, cxcr4 and hhex.
