  • Patent number: 8815598
    Abstract: The present inventors discovered that genes could be introduced specifically into trophectodermal cells with high efficiency, by infecting blastocysts with viral vectors carrying an arbitrary polynucleotide, or by using a nucleic acid transfection reagent in blastocysts, from which zona pellucida (extracellular matrix covering preimplantation early embryos to protect them from infection of viruses and the like) is removed. This method has no risk of infecting cells of the inner cell mass, which develops into a fetus in the future, with the introduced polynucleotide because the trophectoderm serves as a barrier. The present invention provides methods for introducing foreign genes into only placenta but not fetus, which enables rescue of genetically mutant animals from embryonic lethality due to placental abnormality and allows their birth. Furthermore, it is possible to analyze expression and effect of genes that regulate placental formation or placental function by using these methods.

    Abstract: Compositions and methods are provided for making rat pluripotent and totipotent cells, including rat embryonic stem (ES) cells. Compositions and methods for improving efficiency or frequency of germline transmission of genetic modifications in rats are provided. Such methods and compositions comprise an in vitro culture comprising a feeder cell layer and a population of rat ES cells or a rat ES cell line, wherein the in vitro culture conditions maintain pluripotency of the ES cell and comprises a media having mouse leukemia inhibitor factor (LIF) or an active variant or fragment thereof. Various methods of establishing such rat ES cell lines are further provided. Methods of selecting genetically modified rat ES cells are also provided, along with various methods to generate a transgenic rat from the genetically modified rat ES cells provided herein. Various kits and articles of manufacture are further provided.

  • Publication number: 20140234969
    Abstract: The disclosure provides methods for increasing genome stability of an embryonic stem (ES) cell or induced pluripotent stem (iPS) cell, increasing telomere length in an ES or iPS cell, or both, for example by contacting an ES or iPS cell with an agent that increases expression of Zscan4 in the cell. Methods for increasing genome stability or increasing telomere length in a population of ES or iPS cells are provided, for example by selecting Zscan4+ ES or iPS cells from the population of ES or iPS cells (which can include both Zscan4+ and Zscan4? ES or iPS cells). Therapeutic methods of using ES or iPS cells expressing Zscan4 are also provided. Further provided are methods of treating cancer by administering a Zscan4 polynucleotide or Zscan4 polypeptide. Also provided are methods of inducing differentiation of isolated ES or iPS cells into germ cells.

  • Publication number: 20140236267
    Abstract: Photosensitive cardiac rhythm modulation structures and systems are described. A genetically-engineered tissue comprising a population of pacing cells expressing a photosensitive membrane transport mechanism that is responsive to light of a particular wavelength(s) combined with one or more of a light source, a power generator, and a sensor provides pacemaker and/or defibrillator function to a subject. The systems further provide in vitro model systems for electrophysiological studies.

  • Publication number: 20140235498
    Abstract: Disclosed are methods for cell transfection and regulating cellular behavior. More particularly, the present disclosure relates to methods of non-viral cell transfection and regulating cellular behavior using mineral coatings that allow for the enhanced transfection of cells. The mineral coatings bind polynucleotides and provide a source of calcium and phosphate ions to enhance transfection. The present disclosure also provides a high throughput platform for screening non-viral transfection of cells. The methods of the present disclosure also provide an advantageous polynucleotide delivery platform because the mineral coatings may be deposited on various medical device materials after being specifically developed using the high throughput screening platform.
