The "Kozak-CreERT2-P2A" cassette was inserted upstream of the ATG start codon. CreERT2 recombinase is expressed under the regulatory control of Cspg4 gene elements. This model is a Tamoxifen-inducible Cre mouse, and when crossed with mice containing loxP sites, the offspring mice are expected to undergo sequence recombination between loxP sites mediated by Cre recombinase in Cspg4-positive cells (such as vascular pericytes and glial cells) following Tamoxifen induction.
