  • Publication number: 20230292720
    Abstract: The present invention relates to a breeding method for generating gene-edited non-human animals. In particular, the method of the present invention features simultaneous reprograming and gene-editing carried out in somatic cells and subsequent subcloning and genotyping conducted at the in vitro cell stage to obtain precisely gene-edited induced pluripotency stem cells (iPSCs) which are then used in somatic nuclear transfer (SCNT) to generate a precisely gene-edited non-human animal embryo and a resultant gene-edited non-human animal.

  • Patent number: 10414798
    Abstract: A synthetic peptide that targets cancer stem cells is provided. The peptide consists of the amino acid sequence of anyone of SEQ ID NO: 1 to SEQ ID NO: 15. Also provided is a composition comprising said synthetic peptide with a therapeutic agent fused thereto, and a pharmaceutically acceptable carrier or diluent. Further provided is a method of screening a peptide specifically targeting to a cancer stem cell. The method comprises the steps of establishing an oligopeptide library by using a phage expression system, contacting the library with a culture of bulk tumor cells of a cancer cell line, contacting the phages which do not bind to the bulk tumor cells with a culture of cancer stem cells of said cancer cell line, and screening a peptide specifically targeting to a cancer stem cell from the phages which bind to the cancer stem cells.
