Figure 1. Distinct cellular localization of AQP1 was detected in different breast tissues.

Figure 1

(A, B) There was a strongly positive staining of AQP1 in membrane of myoepithelial cells in breast benign lesions, while no expression of AQP1 was observed in ductal glandular epithelial cells. (C, D) There was a strongly positive staining of AQP1 in membrane of myoepithelial cells as well as a weak staining in ductal glandular epithelial cells in breast benign lesions. (E, F) There was a strongly positive staining of AQP1 in membrane of myoepithelial cells in DCIS, while no expression of AQP1 was observed in ductal glandular epithelial cells. (G, H) There was a strongly positive staining of AQP1 in membrane of myoepithelial cells as well as a weak staining in ductal glandular epithelial cells in DCIS. (I, J) High cytoplasmic expression of AQP1 was observed in breast cancer cells in IDC specimens. (K, L) Strong membranous expression of AQP1 with an admixture of less intensive cytoplasmic staining for AQP1. The right panel (magnification 400 ×) is the amplification of the left panel (magnification 200 ×).
