Head-specific genes at 24- to 28-h stage. For each clone we list the name, sequence similarity, and major expression sites; the left panel gives a lateral view, the right panel an anterior/dorsal view. (A, B) 2009/no similariy/telencephalon, tectum. (C, D) 2782/no similarity/ventral retina, hindbrain. (E, F) 3303/pig10-like/forebrain, lateral hindbrain, otic vesicle. (G, H) 3363/fibronectin-like/forebrain, MH boundary, hindbrain. (I, J) 5006/fgf3/MH boundary, cranial ganglia. (K, L) 5035/no similarity/dorsal diencephalon, MH boundary, row of dorsal neurons. (M,N) 5049/ephrin B3-like/widely expressed except rhombomere 3 and 5 (arrowheads). (O, P) 5067/no similarity/telencephalon. (Q, R) 5088/POU domain/widely expressed except telencephalon, especially strong in rhombomere 3 and 5 (arrowheads). (S, T) 5128/no similarity/restricted regions in fore-, mid-, and hindbrain. (U, V) 5150/IGFBP-like/midbrain. (W,X) 5158/KFGF-like/MH boundary, cranial ganglion.
