Galectin-1 is expressed in the adult hippocampus. (A, B) Galectin-1 (A) and nuclear (B) staining in the hippocampus of the galectin-1-null mouse DG. (A', B') High-magnification images of the boxed regions, respectively. No Galectin-1+ cells were detected in the DG of galectin-1 null mutants, indicating that the staining was specific for Galectin-1. (C) Low-magnification images of Galectin-1+ cells in a coronal section of the adult mouse brain. Galectin-1 was expressed in the cortex, SVZ, and hippocampus. (Scale bars: A, B, 500 μm; A', B', 50 μm; C, 1000 μm).
