Research Abstract |
The present study showed the effects of maternal exposure to nanomaterials on the development of cranial nerve system of offspring, using electron microscopic analysis, histological analysis, neurochemical(monoamine) analysis as well as gene expression analysis. The results indicated that exposure of pregnant mice to nanomaterial frequently used in nanotechnology induced alterations of microstructures, monoamine and its metabolism in the brain of offspring during the developmental period. Gene expression analysis using microarray showed an important clue of the mechanisms underlying the effects of maternal exposure to nanomaterials on the brain development.
