We have generated a drug-free, all-in-one dCAS9-SAM vector that can activate endogenous gene expression with the potential to modify cell fate. We demonstrate that this strategy can be used in a number of cell lines and avoids exceptionally high levels of gene expression that are observed in standard transgenic approaches. Compared to the multi-plasmid system, this all-in-one vector activates gene expression to a comparable level but the reduced overall DNA content results in significantly higher viability of transfected cells. This allowed us to use the RUNX1C-GFP human embryonic stem cell reporter cell line to monitor gene activation in individual cells and to show that activation could occur at all stages of the cell cycle.
