  • METHODS AND COMPOSITIONS TO INCREASE HUMAN SOMATIC CELL NUCLEAR TRANSFER (SCNT) EFFICIENCY BY REMOVING HISTONE H3-LYSINE TRIMETHYLATION, AND DERIVATION OF HUMAN NT-ESC
    Publication number: 20180291400
    Abstract: The present invention provides methods and compositions to improve the efficiency of somatic cell nuclear transfer (SCNT) of human cells and the consequent production of human nuclear transfer ESC (hNT-ESCs). More specifically, the present invention relates to the discovery that trimethylation of Histone H3-Lysine 9 (H3K9me3) in reprogramming resistant regions (RRRs) in the nuclear genetic material of human donor somatic cells prevents efficient human somatic cell nuclear reprogramming or SCNT. The present invention provide methods and compositions to decrease H3K9me3 in methods to improve efficacy of hSCNT by exogenous or overexpression of the demethylase KDM4 family and/or inhibiting methylation of H3K9me3 by inhibiting the histone methyltransferases SUV39h1 and/or SUV39h2.
