BMP7 expression in the basal ganglia (A–C), corpus callosum (D, E), and thalamus (F–L). Moderately positive astrocyte-like cells were seen in the globus pallidus (arrowheads in C), and astrocyte-like cells in the corpus callosum (arrowheads in D and E) and reticular thalamus (arrowheads in G) were strongly stained. cc, corpus callosum; CPu, caudate putamen; GP, globus pallidus; LG, lateral geniculate nucleus; MHb, medial habenular nucleus; Po, posterior thalamic nucleus; Rt, reticular thalamic nucleus; VP, ventroposterior thalamic nucleus. Scale bar = 400 μm for F, K; 80 μm for A, D, H, I; 40 μm for B, C, E, G, J, L.
