  • Patent number: 9828630
    Abstract: The present disclosure relates to the use of laminin-521. Laminin-521 can maintain stem cells in vitro pluripotency, enable self-renewal, and enable single cell survival of human embryonic stem cells. When pluripotent human embryonic stem cells are cultured on plates coated with recombinant laminin-521 (laminin-11), in the absence of differentiation inhibitors or feeder cells, the embryonic stem cells proliferate and maintain their pluripotency. Methods of enhancing genetic diagnosis by expanding a single stem cell on laminin-521 prior to PCR amplification are disclosed herein.

  • Patent number: 9763430
    Abstract: Four zebrafish gene promoters, which are skin specific, muscle specific, skeletal muscle specific and ubiquitously expressed respectively, were isolated and ligated to the 5? end of the EGFP gene. When the resulting chimeric gene constructs were introduced into zebrafish, the transgenic zebrafish emit green fluorescence under a blue light or ultraviolet light according to the specificity of the promoters used. Thus, new varieties of ornamental fish of different fluorescence patterns, e.g., skin fluorescence, muscle fluorescence, skeletal muscle-specific and/or ubiquitous fluorescence, are developed.

  • Patent number: 9745598
    Abstract: Targeting constructs and methods of using them are provided for differentiation-dependent modification of nucleic acid sequences in cells and in non-human animals. Targeting constructs comprising a promoter operably linked to a recombinase are provided, wherein the promoter drives transcription of the recombinase in an differentiated cell but not an undifferentiated cell. Promoters include Blimp1, Prm1, Gata6, Gata4, Igf2, Lhx2, Lhx5, and Pax3. Targeting constructs with a cassette flanked on both sides by recombinase sites can be removed using a recombinase gene operably linked to a 3?-UTR that comprises a recognition site for an miRNA that is transcribed in undifferentiated cells but not in differentiated cells. The constructs may be included in targeting vectors, and can be used to automatically modify or excise a selection cassette from an ES cell, a non-human embryo, or a non-human animal.

  • Patent number: 9695445
    Abstract: An objective of the present invention is to provide vectors for conveniently and efficiently producing ES-like cells in which foreign genes are not integrated into the chromosome. The present inventors discovered methods for producing ES-like cells from somatic cells using chromosomally non-integrating viral vectors. Since no foreign gene is integrated into the chromosome of the produced ES-like cells, they are advantageous in tests and research, and immunological rejection and ethical problems can be avoided in disease treatments.
