Neurogenesis in SVZ. The SVZ is shown in the left. Type B1 cells (B1, blue) lie atop ependymal cells (E, green) and extend their processes to blood capillary (BV). Type B1 cells divide to produce type C cells (C, pink). Type C cells then give rise to type A cells (A, red). Type B2 cells (B2, dark blue) also reside in the SVZ. The coronal section in the upper right is shown the diversity of newborn OB interneurons. Deep GCs and CalB⁺ PGCs are derived from ventral NSCs, whereas superficial GCs and TH⁺ PGCs are derived dorsal NSCs. NSCs from the medial wall produce CalR⁺ GCs and CalR⁺ PGCs.
