  • Patent number: 11432537
    Abstract: The present invention discloses a novel means capable of producing a blood chimeric animal in which a state of retaining blood cells originating in a heterologous animal at a high percentage is sustained for a long period of time. The method for producing a non-human animal that retains blood cells originating in a heterologous animal, according to the present invention, comprises transplanting hematopoietic cells of a heterologous animal into a non-human animal, in which hematopoietic cells the function of a gene that acts on the hematopoietic system is modified, The gene that acts on the hematopoietic system is, for example, Lnk gene, When a medium to large mammal is used as a recipient, the survival rate of hematopoietic cells originating in a heterologous animal is dramatically increased such that blood chimerism of 10% or more can be maintained even in a 16 month old animal.

  • Patent number: 11155783
    Abstract: A non-immunogenic selection epitope may be generated by removing certain amino acid sequences of the protein. For example, a gene encoding a truncated human epidermal growth factor receptor polypeptide (EGFRt) that lacks the membrane distal EGF-binding domain and the cytoplasmic signaling tail, but retains an extracellular epitope recognized by an anti-EGFR antibody is provided. Cells may be genetically modified to express EGFRt and then purified without the immunoactivity that would accompany the use of full-length EGFR immunoactivity. Through flow cytometric analysis, EGFRt was successfully utilized as an in vivo tracking marker for genetically modified human T cell engraftment in mice. Furthermore, EGFRt was demonstrated to have cellular depletion potential through cetuximab mediated antibody dependent cellular cytotoxicity (ADCC) pathways.

  • Patent number: 11078460
    Abstract: Fish embryos may be successfully vaccinated or therapeutically treated if the therapeutic agent is injected into the yolk sac. Therapeutic agents may be directly injected or released from microspheres and enter the circulation and tissues. Injection into the yolk sac, combined with the use of carriers, allows for a continued, controlled release of therapeutic agents and processing of antigens. Fish vaccination or therapeutic treatment, selecting fish embryos post fertilization at the one-cell to eyed egg stage of development, and injecting the yolk sac with carriers associated with an antigen(s) or therapeutic agent(s), may be fully automated.
