FOXG1 and chronic kidney disease: In order to study the HC regeneration ability of Foxg1 cKD SCs in the utricle, we injected tamoxifen into Sox9CreER/+Foxg1loxp/loxpRosa26-tdTomato mice, dissected and cultured their utricles in vitro, and lineage traced the SCs after neomycin-induced HC damage (Figure 5A).
