Melanophore integrity mutants show melanophore and iridophore defects.
, 2013 A, B) Dorsal, head images of live wildtype and mutant siblings, 5dpf. Wildtype melanophores maintain dark pigmentation and are now interacting with silver iridescent iridophores (present on eyes and in the center of caudal melanophore patch).

Interplay between Foxd3 and Mitf regulates cell fate plasticity in the zebrafish neural crest [PDF]
, 2010 Pigment cells of the zebrafish, Danio rerio, offer an exceptionally tractable system for studying the genetic and cellular bases of cell fate decisions.

The Effect of The Divalent Cation Ionophore A23187 on Amphibian Melanophores and Iridophores
Journal of Investigative Dermatology, 1977 Calcium ions are required in the medium for the full darkening action of melanocyte-stimulating hormone, but not for its second messenger, cyclic adenosine monophosphate, on isolated frog skin. Thus, the possible effect of the divalent cation ionophore A23187 was studied, using the skin of Rana pipiens.

, 2018 (A) In both D. rerio (r) and D. nigrofasciatus (n), relative areas of the flank covered by interstripe (dense) iridophores was increased in response to Edn3b overexpression (+++) as compared to non-transgenic (–) sibling controls treated identically. The

Fishing for iridophores, catching an oncogene
, 2004 We have a growing understanding of how the neural crest generates melanocytes, but little idea how the other distinct types of pigment cells characteristic of poikilothermic vertebrates are formed.

Edn3 and Ednrb1a mutants of D. rerio.
, 2018 Shown are wild-type (wt) and homozygous mutants for edn3a and edn3b, double mutant edn3a; edn3b, and ednrb1a. edn3a mutants had normal hypodermal pigment pattern, including iridophore interstripes (arrow, right) but lacked peritoneal iridophores ...

, 2013 RPKM values for genes expressed in iridophores at least 30-fold greater than melanocytes and RPE, and 100-fold greater than embryos.

Neon tetra fish (Paracheirodon innesi) as farm-to-optical-table Bragg reflectors [PDF]
Iridophore networks in the skin of neon tetra fish are investigated for use as biologically sourced, tunable, Bragg reflector arrays. This paper reports on a method for immediate and fast post-processing of tissue to modify the structural color of ...

A sox10-dependent tfec/ltk positive feedback loop is required for iridophore specification.
, 2018 WISH to detect tfec (A-H) and ltk (I-L) expression at 30 hpf (A-D, I, J) and 48 hpf (E-H, K, L) in WT and mutant embryos, with quantitation (M,N). At 30 hpf, sox10 mutants (B) lack tfec expression in medially migrating iridoblasts (A, arrows) and instead
