Summary of results and model for stripe and interstripe patterning in zebrafish.
, 2013 (A) Development of pigment pattern phenotypes in wild-type, bnc2 mutants, iridophore-ablated larvae (pnp4a:NTR), and ltk mutants. Blue circles, iridophores; orange circles, xanthophores; grey and black circles, melanophores.

Localized Csf1 expression directed xanthophore development.
, 2013 (A) Ectopic xanthophores (red dashed line) developed over the dorsal myotome in association with Csf1a-expressing cells transplanted from a wild-type, Tg(hsp70l:csf1a-IRES-nlsCFP) donor to a bnc2 mutant host. Larva shown at 7.9 SSL.

SOME NEUROHUMORAL EVIDENCE FOR DOUBLE INNERVATION OF XANTHOPHORES IN KILLIFISH (FUNDULUS)
The Biological Bulletin, 1942 In a majority of over 50 Fundulus majalis tested, the part of a previously faded primary denervated caudal band flanked by two new secondary bands showed pigment dispersal in its xanthophores, as if affected by the stronger dispersal in those of the adjacent secondary bands.

, Involves the Kita and Csf1ra Receptor Tyrosine Kinases
, 2013 Males of the guppy (Poecilia reticulata) vary tremendously in their ornamental patterns, which are thought to have evolved in response to a complex interplay between natural and sexual selection.

, 2014 Variation in pigmentation type and levels is a hallmark of myriad evolutionary radiations, and biologists have long been fascinated by the factors that promote and maintain variation in coloration across populations.

, 2014 A-A’. Dermal fibroblasts strongly rescue melanocytes irrespective of where the clone occurs in the fin. B-C. Skin clones within the melanocyte stripe (B-B’) show more robust melanocyte rescue than skin clones that occur in a xanthophores stripe (C-C’). D.

, 2018 To evaluate the association of the melanotropic peptides and their receptors for morphological color change, we investigated the effects of changes in background color, between white and black, on xanthophore density in the scales and expression levels ...

Summary of melanocyte rescue by pt2-hsp70l>kitlga clones.
, 2014 A. The majority of clones failed to rescue kit-dependent melanocytes in the absence of heat shock induced kitlga expression. Strong rescue was never observed and only 16% of uninduced clones showed weak rescue. B. Following heat shock induction of kitlga,

Experimental Biology and Medicine, 1942 Previous work on killifishes has shown the yellow pigmentary effectors (xanthophores) of Fundulus heteroclitus and F. majalis to be subject to humoral control and to direct, probably double, nervous control permitting independence from melanophore responses.1 A pituitary hormone dominates the xanthophores of the minnow Phoxinus,2 as it does amphibian ...
