Comparison of digital OPT sections with histology sections from the same embryo Digital OPT sections of the CS17 model (a, d and g), viewed using MAPaint software, compared with sections stained using antibodies against GAP43 (b, e and h), and Haematoxylin and Eosin stained sections (c, f and i). In b, e and h, expression is demonstrated by the brown chromagen. Structures of 20 μm in diameter (for example the hypoglossal rootlets) are clearly identifiable, as are the differences amongst a variety of developing tissues. bv, blood vessel; D, diencephalon; drg, dorsal root ganglion (~150 μm); fp, floor plate; H, hindbrain; III, oculomotor nerve; M, midbrain; nh, neurohypophysis (~200 μm by ~50 μm); ov, otic vesicle; r, collapsed roof of 4th ventricle; sc, spinal cord; Vg, trigeminal ganglion (~300 μm by ~150 μm); vl, ventricular layer; X, vagus nerve; Xg, vagus ganglion; XIIroot, hypoglossal rootlets (~20 μm); zli; zona limitans intrathalamica (~100 μm, core is ~30 μm). Scale bars = 200 μm
