Fig 1. Fibronectin expression is upregulated in cav-1 -/- mammary glands.

Fig 1

(A) Immunohistochemistry of fibronectin expression in cav-1 +/+ and cav-1 -/- glands at low and high magnification. Results demonstrated an increased abundance fibronectin fibers surrounding the ducts and in the adipose stroma of cav-1 -/- glands. Fibronectin expression was also localized to the epithelial cells (red arrows) of the ducts in both cav-1 +/+ and cav-1 -/- glands. (B) The percent expression of fibronectin was significantly higher in cav-1 -/- glands compared to cav-1 +/+ glands. (C) The intensity of fibronectin staining was significantly higher in cav-1 -/- glands compared to cav-1 +/+ glands. Scale bars are 50 μM and 20 μM in low and high magnification images, respectively. *p≤0.05. Fn: fibronectin. Results are reported as the mean ± the SEM.
