FOXC1 and psoriasis: Interestingly, both bulge HF‐SC populations (mutantGFP and non‐mutantTom) had reduced mRNA levels of the quiescence transcription factors Foxc1 and Nfatc1 (Horsley et al, 2008; Wang et al, 2016; Fig EV3B and C), suggesting an activation of bulge HF‐SCs during psoriasis progression.
