Krt14 and Mmtv driven GFP expression profile in the BAT. (A–C) Interscapular BAT from the virgin, lactation and involution stages of the Krt14-Cre-ROSAmTmG mice were sectioned and immunostained for GFP, Perilipin1 and LipidTOX. (D) The percentage of adipocytes express Krt14-GFP in different stages. (E–G) Interscapular BAT from the virgin, lactation, and involution stage of the Mmtv-Cre-ROSAmTmG mice were sectioned and immunostained for GFP, Perilipin1, LipidTOX and PPAR-γ. (H) The percentage of adipocytes express Mmtv-GFP in different stages.
