Fig 3. Cell populations and vasculature of supraoptic nucleus at the somatic zone.

(A, A') Parenchymal glial cells are distinguished as two groups: cells having smooth rounded nuclei and vesicles similar to lipid droplets (asterisk) (A) and cells with polylobed nuclei containing lipid droplets or endosomes in the cytoplasm (asterisk) (A'). (B)The supraoptic nucleus is richly vascularized. Capillaries (asterisks) are abundant and sometimes close to MNs. (B') Endothelial cells (light asterisks) and pericyte (dark asterisk) of capillaries. bl: basal lamina.
