  • Supplement for cultivation of mammalian embryos
    Patent number: 10485584
    Abstract: Media, kits, and methods for cultivation of mammalian embryos from fertilized oocyte stage to blastocyst stage in the presence of N-benzyl-3,5-dicarbethoxy-4-phenyl-1,4-dihydropyridine. The use of this supplement improves the early embryonic development, in particular the quality of zygotes and the blastocyst formation. The supplemented media can be used with pigs, humans, or other mammals N-benzyl-3,5-dicarbethoxy-4-phenyl-1,4-dihydropyridine may be added to known media, and used for with vitro fertilization methods.
    Type: Grant
    Filed: June 8, 2017
    Date of Patent: November 26, 2019

  • Inorganic pyrophosphate and uses thereof
    Patent number: 10070889
    Abstract: The present invention provides a new and improved sperm stimulating additive comprising a certain amount of inorganic pyrophosphate (PPi). Addition of PPi in the media for human/animal in vitro fertilization (IVF) improves fertilization rate; addition of PPi in the semen extender for farm animal artificial insemination (AI) may improve pregnancy rates; furthermore, mammalian oocytes matured in vitro in a medium including PPi attain improved fertilization and developmental potential, while embryos cultured in medium supplemented with PPi have improved development to blastocyst.
    Type: Grant

    Date of Patent: September 11, 2018
    Assignee: The Curators of the University of Missouri

  • INORGANIC PYROPHOSPHATE AND USES THEREOF
    Publication number: 20140350329
    Abstract: The present invention provides a new and improved sperm stimulating additive comprising a certain amount of inorganic pyrophosphate (PPi). Addition of PPi in the media for human/animal in vitro fertilization (IVF) improves fertilization rate; addition of PPi in the semen extender for farm animal artificial insemination (AI) may improve pregnancy rates; furthermore, mamalian oocytes matured in vitro in a medium including PPi attain improved fertilization and developmental potential, while embryos cultured in medium supplemented with PPi have improved development to blastocyst.
