Distribution of SR-101 in the cervical spinal cord 20 min after intracisterna magna (i.c.m.) injection in rats. SR-101 was administered without inhibitor (A, B). The fluorescence signals of SR-101 were predominantly detected in the leptomeninges at the surface of the spinal cord. The fluorescence intensity of SR-101 was diminished in the leptomeninges and instead increased in the parenchyma of the spinal cord pre-administered with taurocholate (C, D) and digoxin (E, F). Scale bars: 300 μm. Subfigures B,D,F are enlarged spinal cord images of A,C,E, respectively. The figure was reprinted (adapted) with permission from reference (35).
