title: [Expression of glial fibrillary acidic protein in the developing human brain].
abstract: It was shown that the glial fibrillary acidic protein (GFAP) content in developing (fetal) human brain is sharply increased. The expression of GFAP was observed already on the 7th-8th week after gestation, the GFAP concentration being less than 0.05% in comparison with adult brain. GFAP can be immunohistochemically detected in radial glial cells. At early stages of development the presence of antigenic determinants of 68 kDa and 100 kDa polypeptides interacting with monoclonal antibodies alongside with native GFAP (51 kDa) and its low molecular weight forms was demonstrated. These antigenic determinants cannot be detected at later stages of development and are absent in adult brain. The data obtained testify to changes in the gene expression of intermediate filament proteins at early stages of human brain ontogenesis.
