(A) Lipocalin 2 (LCN2) immunoreactivity in the ipsilateral basal ganglia after a sham operation, and in the contra- and ipsilateral basal ganglia of wild-type (WT) mice at 24 hours after intracerebral hemorrhage (ICH). Scale bar=50 μm; and LCN2 protein levels in the ipsilateral basal ganglia at 24 hours after ICH or sham operation. Values (ratio to β-actin) are means±s.d.; n=7 for each group, #P<0.01 versus the sham group. (B) Double labeling of LCN2 with GFAP (astrocyte marker), Iba-1 (microglia marker), NeuN (neuronal marker), and CD31 (endothelial marker) in the ipsilateral basal ganglia at 24 hours after ICH in WT mice. Scale bar=20 μm.
