Fractional glomerular arborization of clasping and periglomerular cells. (A) Schema of the three analyzed parent glomerulus' volumes: an outer shell comprising directly adjacent juxtaglomerular cell bodies (thickness 15 μm; green), an inner shell (thickness 15% of the mean glomerular radius; yellow) and a core region (red; see methods). (B) Fractional arborization patterns of the PGCs and CCs [and additional rat mitral cells (MCs)]: Intraglomerular dendritic voxel number divided by the outer shell number for all pooled cells (left), or separated by species (middle and right). (C) Fractional arborization of the same cell types in the combined shell volume (inner + outer shell), relative to the total juxtaglomerular and glomerular volume (shells + core), again pooled (left) or separated by species (middle and right). ^**P < 0.01; ^***P < 0.005, Mann-Whitney-Test.
