Figure 6

Expression of Nvi-Hox2 during postlarval development (a) and regeneration (b–q). Anterior is directed upwards on all panels. All views are ventral. (a) Expression pattern of Nvi-Hox2 in juvenile worm during normal growth. Expression forms a ring in ectodermal and mesodermal tissues of the GZ. Red arrowheads mark single-cell expression domains in segment ectoderm. Expression of Nvi-Hox2 at 0 hpa (b, j), 4 hpa (c, k), 10 hpa (d, l), 18 hpa (e, m), 24 hpa (f, n), 48 hpa (g, o), 3 dpa (h, p) and 7 dpa (i, q). Black asterisks mark background in the gut. Magnification 20×. For details, see text.
