摘要： This application provides improved methods of editing the genome of a target cell. Cas9 molecules can be used to create a break in a genomic region of interest. To increase the likelihood that the break is repaired by homology-directed repair (HDR), the cell can be contacted with an HDR-enhancer. The cell may be, e.g., a human cell, a non-human animal cell, a bacterial cell, or a plant cell.

摘要： Methods of culturing embryonic stem cells, induced pluripotent stem cells and/or differentiated cells in culture medium comprising activin are described. In one aspect, the disclosure features a pluripotent human stem cell, wherein the stem cell comprises: (i) a genomic edit that results in loss of function of Cytokine Inducible SH2 Containing Protein (CISH) and (ii) a genomic edit that results in a loss of function of an agonist of the TGF beta signaling pathway, or a genomic edit that results in a loss of function of adenosine Ata receptor.
