Local rescue of xanthophore numbers and organization by xanthophores in pfeffer hosts.

(a–c) Restoration of normal number and organization of xanthophores in pfeffer. (d,e) Xanthophores spread into neighbouring xanthophore-devoid segments as coherent net. Dashed red line: border of transplanted cluster. (f–k) Restoration of the striped pattern by interactions between the xanthophore cluster and the host melanophores. (f–k) Widely distributed melanophores (black) become organized into stripes on increase in number of xanthophores and their compaction in the light stripe region. Red arrow: a cluster of melanophores that is cleared over time; red arrowhead: xanthophores retracting from dark stripe region. Dashed red line: border of the cluster showing xanthophores-positive area with rescued pattern on the left, no rescue on the right. (l) Chimera obtained by transplantation of Tg(pax7:GFP) into pfeffer;brass. The xanthophore cluster covers 17 metamers, whereas the melanophores cluster covers 4 metamers. Xanthophores—green, Tg(pax7:GFP). Dashed red line: border of melanophores cluster. Scale bars, a–k: 100 μm, l: 250 μm.
