Abdominal mammary glands were harvested from Plg-RKT+/+
(A,C,E,G) and Plg-RKT−/−
(B,D,F,H) female mice two days following postpartum and stained with trichrome (blue) (yellow arrows label representative infiltrating cells) (A,B), anti-F4/80 against macrophages (black arrows label representative macrophages) (C,D), anti-fibrin(ogen) (the curved yellow arrow labels representative fibrin deposition in alveoli; the curved orange arrow labels representative fibrin deposition in dilated ducts; the straight yellow arrows labels representative fibrin deposition in adipose tissue) (E,F), or non-immune rabbit IgG control (G,H). For A, B, G,H, images were obtained with a Keyence BZ9000 (magnification X 400). For C–F, Images were obtained with a Keyence BZ-X700 (A–H magnification X 200). For the inset in panel D, (magnification X 400).
