The unique properties of human embryonic stem (hES) cells render them invaluable for many scientific and clinical endeavors. Wider application of hES cells requires a comprehensive understanding of their biology that can be dissected using RNA interference-based gene silencing. However, commonly used transfection methods to deliver nucleic acids into a cell often lead to differentiation of hES cells. For that reason, effective transfection technique with minimal side effects is essential for studying and employing hES cells. Here, we describe a CPP-based method for targeted gene silencing in hES cells using siRNA complexed with PepFect 14 (PF14). This approach results in effective downregulation of mRNA and protein levels of a target gene without adverse effects on cell viability and pluripotency. © 2022.
