Fig. 2.

Adjacent coronal sections of a P7 striatum incubated with ephrin-A4–Fc (A) and ephrin-A1–Fc (B) fusion proteins. Both ligands produce an identical mosaic binding pattern within the striatum. Small patches with little or no binding (asterisks) are superimposed in adjacent sections for both ligands. In addition, there is a narrow band of neuropil located below the corpus callosum and external capsule (arrowheads) that lacks binding. Scale bar, 500 μm.
