Fig. 1From: A matrisome RNA signature from early-pregnancy mouse mammary fibroblasts predicts distant metastasis-free breast cancer survival in humans(A) Hematoxylin/eosin staining of representative (n = 3 animals) 3-days pregnant mouse inguinal mammary glands (P3 A-C) show the histological changes compared to age-matched adult virgin glands (Ctrl A-C) of denser stromal adipose tissue () and wider ECM layer around epithelium (). Scale bars are 250 µm (B) Immunohistochemical analysis of 3-days pregnant mouse (n = 1 animal, 4th gland) mammary gland and age-matched adult virgin glands showing the changes of matrix- and basement membrane-associated proteins (COLI, COLVI, BMP1, FBLN2, FBLN5, and AGRN).
