Aggrecan wholemount gene expression demonstrates that a patterned organization to the chick brain VZ continues after neurogenesis is largely complete. A, Midline cut displays heterogeneities in aggrecan mRNA distributions in the right brain VZ of the E8 chick embryo. Dorsal is to the top and rostral is to the left. Arrow marks the prospective olfactory bulb. B, C, Dorsal view of late E7 (B) and E8 (C) hindbrains oriented with rostral to the top. Arrow in B points to labeling in rhombomere 4. D, Dorsal view of E8 ventral midbrain, with the prospective midbrain tectum resected. Arrows point to arcuate territories in VZ gene expression patterns. Arrowhead identifies dense labeling of the isthmus. di, diencephalon; hb, hindbrain; mb, midbrain; ob, obex; tel, telencephalon;
