A Protocol to Produce Genetically Edited Primary Oral Keratinocytes Using the CRISPR-Cas9 System.

The Nobel Prize awarded gene editing system, CRISPR-Cas9, is probably one of the greatest achievements of the last decades. CRISPR-Cas9 can introduce irreversible genomic changes in its target DNA by simple specifying a 20-nucleotide sequence within its RNA guide. Due to its simplicity, efficacy, and relative low cost in comparison with other genome editing systems, it has become the most common gene editing system used in research laboratories. Here we describe a step-by-step protocol to produce genetically edited primary oral keratinocytes using the CRISPR-Cas9 system.
