Fig 2. Tenascin-C expression is upregulated in cav-1 -/- mammary glands.

(A) Immunohistochemistry of tenascin-C expression in cav-1 +/+ and cav-1 -/- glands at low and high magnification. Results demonstrated an increased expression of tenascin-C in the peri-ductal and adipose stroma in cav-1 -/- glands. This is in contrast to cav-1 +/+ glands where tenascin-C expression is expressed in the peri-ductal stroma and to a lesser extent in the adipose stroma. Tenascin-C was also expressed in the stromal cells in cav- 1-/- and cav-1 +/+ glands (red arrows), albeit with a greater proportion of positive cells in cav-1 -/- glands. (B) The percent expression of tenascin-C was significantly higher in cav-1 -/- glands compared to cav-1 +/+ glands. (C) The intensity of tenascin-C 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, **p≤0.01. Tn-C: tenascin-C. Results are reported as the mean ± the SEM.
