Galectin expression in the endothelium of different human tissues. Immunohistochemical staining of galectin expression in different human tissues, ie, placenta (A, E, I, M, and Q), liver (B, F, J, N, and R), kidney (C, G, K, O, and S), and colon (D, H, L, P, and T). As positive vessel staining, CD31/34 was used (A–D, brown staining). Staining was performed for galectin-1 (E–H), galectin-3 (I–L), galectin-8 (M–P), and galectin-9 (Q–T). Each inset shows the endothelial cells in more detail with asterisks marking the luminal site of the vessel. The lower inset in A–D shows the negative control in which the primary antibody was omitted.
