(A) Representative hematoxylin and eosin (H&E) and immunofluorescent stains of dorsal skin sections from CAGrtTA3/+; TtG-Ren.713 and CAG rtTA3/+; TtG-Brd4.552 mice on the dox diet for 2 weeks, showing hair shaft defects and epithelial hyperplasia. The bottom panels show dorsal skin sections in CAGrtTA3/+; TtG-Brd4.552 mice following 5 weeks of dox treatment and 2 weeks of subsequent dox withdrawal. Scale bars are indicated.
(B) Image of a CAGrtTA3/+; TtG-Brd4.552 and littermate control CAGrtTA3/+; TtG Ren.713 mouse following 5 weeks of doxycycline treatment and 2 weeks of subsequent dox withdrawal.
(C) Full-thickness scans of H&E-stained dorsal skin sections from CAGrtTA3/+; TtG-Ren713 and CAGrtTA3/+; TtG-Brd4.552 mice after 2 weeks of dox treatment (left and middle) and CAGrtTA3/+; TtG-Brd4.552 skin after 5 weeks of dox treatment and dox withdrawal (right).
