Barcoding works by integrating unique DNA sequences into the genome of individual cells. These sequences serve as identifiers, much like barcodes on products in a store. Techniques such as CRISPR-Cas9 and lentiviral vectors are commonly used to introduce these barcodes. Once the cells are tagged, they can be tracked through various high-throughput sequencing methods to study their growth, differentiation, and response to external factors.
