Sebaceous gland differentiation. Immunofluorescence staining of wild type (WT) and ∆K5ΔNβ-cateninER (ΔK5) transgenic back (A–C) and tail (D) skin following 21 days of 4OHT treatment. Skin in (C) was left untreated for a further 21 days. Sections were labeled with antibodies fatty acid synthase (red) and keratin 14 (green), with DAPI nuclear counterstain (blue). Asterisks indicate fatty acid synthase positive regions. Arrows in (B) indicate ectopic HF arising from SG. Arrows in (D) indicate cysts. Scale bar: 50 µm.
