Figure EV1. Characterization of c‐JUN/JUNB in distinct hair follicle stem cell populations from scalp psoriasis patients (related to Fig 1).

• A
  Confocal images of the bulge region of human psoriatic hair follicles from non‐lesional and lesional regions of the scalp. CD200 (green), c‐JUN (red), DAPI (blue).
• B, C
  Representative composite immunofluorescence images of whole hair follicle units by confocal from non‐lesional and lesional scalp psoriasis patients (B) and magnification images of specific regions from the HFs (C). c‐JUN (green), JUNB (gray), GATA‐6 (red), and DAPI (blue). Yellow arrows represent the outer root sheath basal layer in the bulge (R1, R3) and proximal bulb (Pb, R2, R4). Yellow asterisks represent overexpression of GATA‐6 in suprabasal layers of the outer root sheath in lesional bulge region.
