Cellular Organization and Migration Pathways of the Ventricular-Subventricular Zone in the Juvenile Swine Brain (Sus scrofa domesticus).

The ventricular-subventricular zone (V-SVZ), lining the lateral walls of the lateral ventricles, is a major neurogenic region in the adult brain of many mammals. This study investigates the structural organization and cellular composition of the V-SVZ in the juvenile swine brain (3-5 months), providing novel insights into neuroblast migration in gyrencephalic species. Using immunohistochemistry combined with transmission and scanning electron microscopy, we redefined the cytoarchitecture of the swine V-SVZ, identifying four distinct cellular layers.
