... cellular morphogenetic programs of photoreceptors and interommatidial pigment cells (IOPCs) organize tissue pattern to support retinal integrity. Our experiments show that photoreceptor and IOPC terminal differentiation is unexpectedly interdependent, connected by an intercellular feedback mechanism...

... is required only in melanophores for interactions with xanthophores and iridophores, which cause location-specific pigment cell shapes and thereby influence colour pattern and contrast in D. rerio . Cis-regulatory rather than protein coding changes underlie kcnj13 divergence between the two Danio species. Our...

... hypothesis of zebrafish pigment cell development refutes this view. We propose a novel ‘cyclical fate restriction’ hypothesis, based upon a more dynamic view of transcriptional states, reconciling the experimental evidence underpinning the traditional hypotheses. * Author for correspondence ( bssrnk...

...Yuu Usui; Toshihiro Aramaki; Shigeru Kondo; Masakatsu Watanabe ABSTRACT Connexin 39.4 (Cx39.4) and connexin 41.8 (Cx41.8), two gap-junction proteins expressed in both melanophores and xanthophores, are crucial for the intercellular communication among pigment cells that is necessary for generating...

Pearson Many pigment cells acquire unique structural properties and gene expression profiles during animal development. The underlying differentiation pathways have been well characterized in cells formed...

...Melissa L. Harris; Ronelle Hall; Carol A. Erickson Neural crest cells that become pigment cells migrate along a dorsolateral route between the ectoderm and the somite, whereas most other neural crest cells are inhibited from entering this space. This pathway choice has been attributed to unique...

...Hiroki Nishida ABSTRACT Tadpole larvae of ascidians have a brain and two kinds of sensory pigment cells within the brain. These neural tissues are formed through folding of the neural plate and, as in vertebrates, neural induction is involved in the formation of the nervous system. The brain...
