A) We investigated the location and types of cells in Cx, St, Sp that were clonally related to the different subtypes of OB neurons. B–C) Example of a clone (P28-Q128R-C4) containing a mGFP+/TdT+ superficial GC (arrow in B) and a GFP+ neuron found in cortex (C). D–G) Neurolucida® 3D reconstructions of a radial clone in cortex (red symbols from E11.5 retroviral injection; P28-Q128R-C4 in D)), septum (green symbols from E13.5 retroviral injection; Q057-C3 in E), and striatum (green symbols from E13.5 retroviral injection; F and G). Striatal clones can be further distinguished as radial (Q056R-C3 in F) and horizontal (Q057R-C14 in G). Neurons (·), astrocytes (□), and ependymal cells (◆) are shown. The forebrain surface (gray), lateral ventricle (blue), and the corpus callosum (green) are shown. H–L) Relative OB positions of individual cells in the OB were grouped and classified according to their clonal relationships to cortical (H), septal (I), or radial (J), single-cell (K), or horizontal (L) striatal clones. Closed circles and crosses denote CalR negative and positive cells, respectively. ψ denotes a type-2 cell in Q057R-C9 (in J). The expected correlation based on the previous mapping of the postnatal V-SVZ (; ) is indicated by a + or −. “n.d.” indicates that cell subtype was “not determined” due to technical limitations (see Methods), but these cells were CalR-negative as expected. Asterisks in H, I, J, and L mark Neurolucida® reconstructed clones in D, E, F, and G, respectively. For additional examples, see . Scale bars represent 25 and 50 μm in B and C, respectively.
