Three of them showed a typical banded pattern, with two main transverse expressing zones located just rostrally and just caudally to the Wnt-producing zli.
A telencephalic Fgf8/17 domain could only be detected at stage 27, at the rostral tip of the telencephalon, together with additional expressing zones in the hypothalamus and dorsal diencephalon (Fig. 6G, H), which recapitulates the archetypal gnathostome "early" Fgf8 pattern.
For the central expressing zone, we used a window of 40 × 10; for the lateral nonexpressing zone, we used a window of 30 × 10.
Similarly to FoxG1, low Fgf8 expression is revealed in non-telencephalic cells of outer layer, in which Ras-dva1 is also expressed (zone 2 in Fig. 2A2,A4,B2,B4; zone 2 in supplementary material Fig. S1J,K2,K4).
These tectonic features are either high trends (expressing anticlinal zones or swell-like belts) or low trends (referring synclinal zones or trough-like belts) and fault trends (throwing from the high trends to the low trends).
We compared the expression of genes found in zone I to genes expressed in zones II and III, and finally between zone II and zone III.
Indeed, Dlx5 was expressed throughout the Col2a1-expressing zones of the long bones and vertebrae (Fig. 2F–I and data not shown), including the resting and proliferating zones of the long bone epiphyses, where its expression is not usually detectable (compare Fig 2H,I).
Fibronectin, but not laminin, is expressed in zones of vasculogenesis immediately prior to vessel formation.
Thus, its knockout leads to a pericentralization of hepatic functions, e.g. the extension of the small pericentral glutamine synthetase-expressing zone to the entire parenchyma (Benhamouche et al. 2006; Gebhardt and Hovhannisyan 2010).
If the Rorb-expressing zone in M1 is similarly organized, then neurons in that laminar location should receive strong TC input from the primary motor thalamic nuclei, particularly the ventrolateral nucleus (VL).
Expressed superficial zone protein was 3-fold greater in the superficial zone population than in the growth zone population (p<0.01).
