Genetic lineage tracing is accomplished using bi-transgenic mice, where one allele is altered to express Cre recombinase, and another allele encodes a Cre-dependent genetic reporter protein. Once Cre is activated (constitutive or in response to tamoxifen), the marker gene-expressing cells become indelibly labeled by the reporter protein. Therefore, daughter cells derived from labeled cells are permanently labeled even if the marker gene that drove Cre recombinase expression is no longer expressed in these cells. This system is commonly used to label putative progenitor cells and determine the fate of their progeny. Here, we describe the use of c-kit-based genetic lineage-tracing mouse line as an example and discuss caveats for performing these types of experiments.
