Fig 5. Reelin and Dab 1 expression in the olfactory system.

Fig 5

(A-C) Adjacent sections in a CS 17 embryo. (A) The migrating cells in the mesenchyme are well delineated (arrow) in front of the telencephalon which shows a thick proliferating ventricular zone and the developing marginal zone. (B) Reelin is present in the OE, the migrating cells in the mesenchyme and in the marginal zone of the basal telencephalon. (C) Dab 1-expressing cells are present in the migratory mass but not in the OE and the marginal zone. (D-F) Near adjacent sections in a CS 18 embryo. (D) Beta-III tubulin-positive cells are present in the OE, in the presumptive VNE (arrow) and in the cells leaving the presumptive VNE. (E) Reelin is only present in the presumptive VNE and in the cell stream leaving the VNE. (F) Higher magnification of the presumptive VNE: Dab 1 is present in the stream leaving the presumptive VNE but not in the epithelium. (G-I) Adjacent sections at CS 20. (G) Calretinin-positive cells are present in the VNE and in the migrating cell stream leaving the epithelium. (H) Only weakly Reelin-labeled cells are present in the migrating cell stream. (I) Dab 1 is present in the migrating cell stream but not in the VNE. Abbreviations: (cal) calretinine immunostaining, (CS) Carnegie stage.
