Forebrain progression of A2bp1 label from E14.5 demonstrates the rapid rise in A2bp1 expression in the cortex and persistent expression in postmitotic cells of the basal forebrain. Medial to the external capsule (ec), ample expression is evident in the striatum, while lateral to the ec, there is expression in the lateral migratory stream (lms), which is relatively light compared to the darker labeling in the cortical plate (CxP). Labeling is still apparent in cranial nerves (cnV and cnVII). Scale bar = 1 mm.
