Figure 1.

Thalamocortical axons expressed NCAM and PSA at E14.5. Sections containing DiI-labeled TC axons were labeled with antibodies to the intracellular domains of large NCAM isoforms (A) and PSA (B). Insets show the regions analyzed. A', A” and B and B” show the detection channels separately. Note that the red signal of DiI labeled axons in the ventral telencephalon coincided in all cases with the green signal corresponding to NCAM (A–A”) or PSA (B–B”) immunoreactivities. Maximum projections of confocal microscope stacks. DT, dorsal thalamus; ctx, cortex. Bars in A, B, 200 μm; insets, 100 μm.
