  • Patent number: 9238795
    Abstract: This invention relates to the production of populations of Smooth Muscle Cells (SMCs) of specific embryonic lineages, such as neuroectodermal and mesodermal SMCs. Pluripotent stem cells are cultured in one or more lineage induction media to produce progenitor cells of a defined embryonic lineage, which are then cultured in an SMC induction medium to produce a population of SMCs of the embryonic lineage. Populations of SMCs of defined lineages may be useful, for example, in accurately modelling vascular disease.

  • Patent number: 9157067
    Abstract: The invention relates to the isolation and propagation of pluripotent cells isolated from the mammalian late epiblast layer, termed Epiblast Stem Cells (EpiSCs). These cells are useful in a range of applications, including the generation of transgenic animal species.

  • Patent number: 8323971
    Abstract: This invention relates to the culture of pluripotent cells in a fully humanised chemically defined medium. Cells may be cultured over a prolonged period of time without losing their pluripotent status or may be controllably induced to differentiate into progenitor cells of the three primary germ layers by the addition of differentiation factors, for example differentiation factors which modulate one or more of the Activin/Nodal, FGF, Wnt or BMP signalling pathways.

  • Patent number: 6127598
    Abstract: The present invention features mouse models for Nkx-2.2 gene function and for Nkx-6.1 gene function, wherein the transgenic mouse is characterized by having a defect in Nkx-2.2 gene function or a defect in Nkx-6.1 gene function (where, because Nkx-2.2 acts upstream of Nkx-6.1, a defect in Nkx-2.2 gene function affects Nkx-6.1 gene function) and by having a decreased number of insulin-producing cells relative to a normal mouse. Where the transgenic mouse contains a defect in Nkx-2.2 gene function, the mouse is further characterized by a decreased number of serotonin-producing cells relative to a normal mouse. The transgenic mice may be either homozygous or heterozygous for the Nkx-2.2 or Nkx-6.1 defect.
