Applying CRISPR-Cas9 Technique to Knock Out Foxj1 in Mouse Tracheal Epithelial Progenitor Cells
Tianhao Xu
CRISPR–Cas9 has triggered a revolution in which laboratories around the world are using the technology for innovative applications in biology. CRISPR can efficiently and precisely target, modify, regulate and mark genes in cells and in organisms. To establish a CRISPR genome editing platform, accumulating hands-on experience of applying such technique is necessary. In this experiment, foxj1 has been selected as the target gene as it is essential for ciliated cells formation and its function has been well understood. The whole experimental procedures include: design mfoxj1 sgRNA, sub-cloning lentiCRISPR-Cas9 vector, confirming sgRNA insertion by sequencing, packaging lentiCRISPR-Cas9 capsids, transfecting mouse tracheal epithelial progenitor cells and evaluating the knock-out results. Although the knock-out results are not available now, previous experimental procedures have provided valuable experience, which can facilitate to establish a CRISRP gene editing platform in the laboratory.
