In contrast to the well understood role of reelin signalling, relatively little is known about the identity of the reelin).
In addition, the caudomedial wall of the telencephalon, including the cortical hem, is a major source of a CR cell population which is characterized by the expression of reelin, p73, Calretinin and glutamate ( Meyer ., 2006).
Here some pictures of initial tests, cell nuclei are stained with DAPI in blue, zif268 is shown in green and Brd U in red.
At E15.5, there was a significant increase in cell death in the Dicer null cortex and the majority of apoptotic cells in the Dicer null cortex were located in the VZ.The cat FISH (cellular Compartment Analysis of Temporal activity by Fluorescence In Situ Hybridization) method allows us to trace back when a specific neuron has been activated.By using labeling for the RNA of the immediate early gene (IEG) zif268 for example, we know that when we detect its RNA in 2 punctae in the nucleus, zif268 gene transcription was initiated 5min ago.Surprisingly, both mutants show normal cortical lamination except for the caudal cortex, suggesting that hem derived CR cells are not required to control cortical layering and that other sources of reelin, particularly cortical plate (CP) interneurons, are sufficient to allow lamination to proceed (). the formation of the subplate (SP) and the marginal zone (MZ) is severely disrupted in these animals making it difficult to study cortical lamination.To circumvent these difficulties, we made use of the compound heterozygous animals were kept on a mixed C57Bl6/C3H and C3H/He background, respectively, and were interbred.
The Neuroscience Track seeks to produce neuroscientists with both specialized knowledge and a broad-based understanding of the discipline. During their first year, students in the Neuroscience Track follow a course of study designed jointly by both graduate programs that provides suitable preparation for either path to a Ph.
