CXCR4/SDF1 Signaling Is Dysregulated in the Aging V-SVZ
(A) Numbers of EdU-positive cells in V-SVZ whole mounts in 2-month-old and 12-month-old mice (n = 4; ∗∗p < 0.01 by Student's t test).
(B) qRT-PCR analysis of Cxcr4 and Sdf1 expression in the V-SVZ of young and aged mice (n = 4/group).
(C) Representative confocal images of CXCR4 immunohistochemistry in coronal sections of the V-SVZ in 2-month-old and 12-month-old mice. Scale bars, 50 μm.
(D) Distribution of proliferating cells relative to Sdf1DsRed-positive vasculature. n = 5,793 cells for young mice, n = 2,208 cells for aged mice measured in 4 mice (∗∗∗∗p < 0.001 by Mann-Whitney test).
