Regional and laminar differences in antigen profiles and spatial distributions of astrocytes in the mouse hippocampus, with reference to aging

▶ The astrocyte heterogeneity is of growing interest, reflecting their diverse roles. ▶GFAP-negative astrocytes are seen in str. pyramidale and lucidum of ventral CA3. ▶S100β-negative astrocytes are mainly located in hilus of dentate gyrus. ▶Astrocyte numbers show age-related changes in specific layers of the hippocampus.
