Workflow for Performing Genetic Manipulation in Human Trophoblast Stem Cells Using CRISPR/Cas9 Technology

Clustered regularly interspaced short palindromic repeats (CRISPR)/Cas9-based tool kits greatly facilitate the investigation of gene function, especially gene editing and transcriptional regulation technology. Human trophoblast stem cell (hTSC) is a promising cell model for simulating the development and function of human placental trophoblast cells. Here, we provide an optimized workflow for efficient genome editing and transcriptional activation in hTSCs using a lentivirus-dependent method. We also present methods to evaluate the gene targeted mutations and transcriptional activation.
