Iridophores and not carotenoids account for chromatic variation of carotenoid-based coloration in common lizards (Lacerta vivipara) [PDF]
, 2012 Carotenoids typically need reflective background components to shine. Such components, iridophores, leucophores, and keratin- and collagen-derived structures, are generally assumed to show no or little environmental variability.

On the role of TFEC in reptilian coloration
Frontiers in Cell and Developmental BiologyReptilian species, particularly snakes and lizards, are emerging models of animal coloration. Here, I focus on the role of the TFEC transcription factor in snake and lizard coloration based on a study on wild-type and piebald ball pythons.

Model for neural origins of metamorphic melanocytes and iridophores.
, 2013 All pigment cells are highly likely to originate from embryonic neural crest, but pigment cells in the embryo and early larva have lineages distinct from pigment cells in the adult.

Changes in the ventral dermis and development of iridophores in the anadromous sea lamprey, Petromyzon marinus, during metamorphosis: an ultrastructural study [PDF]
, 1992 The ultrastructural changes that take place in the ventral dermisalong with the development of iridophores were examined in the anadromous sea lamprey, Petromyzon marinus, during metamorphosis.

Phylogenetic relationship and pigment patterns of D. rerio and D. nigrofasciatus.
, 2018 (A) Phylogenetic relationships of selected Danio species [9]. (B) Danio rerio exhibit several dark stripes of melanophores with sparse iridophores, and light interstripes with abundant iridophores.

Regulation of zebrafish melanocyte development by ligand-dependent BMP signaling
eLife, 2019 Preventing terminal differentiation is important in the development and progression of many cancers including melanoma. Recent identification of the BMP ligand GDF6 as a novel melanoma oncogene showed GDF6-activated BMP signaling suppresses ...

Detection of developing iridophores using expression of tfec.
, 2018 (A) Chromogenic WISH identifies tfec transcription in positions matching iridophore (iph) positions at 72 hpf. Images show the posterior trunk of the same individual, live and post-WISH processing.
