Homozygotes of a mouse strain with genetic polydactyly (Pdn) show disrupted cortical lamination and a significant decrease of S-100beta-immunoreactive elements in a particular area of the brain. In order to understand the abnormal cortical formation at the cellular level, the migration of cortical neurons and the development of glial cells were studied using bromodeoxyuridine (BrdU), S-100beta, and glial fibrillary acidic protein (GFAP) immunohistochemistry. Homozygous mice (Pdn/Pdn) displayed a variable pattern of abnormalities. Irregular GFAP-positive radial glial cells and disturbance of neuronal migration were found in a circumscribed area of the caudo-dorsal cortex of newborn Pdn mouse. The number of S-100beta-positive cells was reduced in this area. The present results suggest that abnormal cortical lamination closely correlates with disturbance of neuronal migration and abnormalities of glial cells, especially a significant decrease of S-100beta-immunoreactive cells.
