Retinal decussation patterns in pigmented and albino ferrets
Neuroscience, 1987The decussation patterns of retinal ganglion cells in adult pigmented and albino ferrets were determined from the distribution of cells labelled after large unilateral injections of horseradish peroxidase into the visual pathway, involving the lateral geniculate nucleus and fibres of passage to the superior colliculus. About 6000 retinal ganglion cells

Pigment Cell Pattern Formation
2017In this chapter, an LGCA is introduced as model for pattern formation in salamander larvae. After providing the biological background the model is defined and tested by means of simulations. Model results demonstrate that the larval stripe pattern can arise solely as a consequence of direct cell interactions.

Pattern Formation by Coupled Oscillations: The Pigmentation Patterns on the Shells of Molluscs
1987The diversity and beauty of the pigmentation patterns on the shells of snails and bivalved molluscs invites us to construct models to understand their formation. The similarity of patterns in unrelated species on the one hand and the diversity in closely related species on the other encourage the assumption that most of them are generated by a common ...

Cell projections set up pigment pattern
Science, 2017Cell Signaling Macrophages eliminate dead or dying cells and identify and destroy invading microbes. However, they also exhibit nonimmune functions in development and homeostasis. Eom and Parichy show that macrophages are essential for postembryonic remodeling during adult pigment stripe formation in zebrafish (see the Perspective by Guilliams ...

Patterned dystrophies of the retinal pigment epithelium: A review
Ophthalmic Paediatrics and Genetics, 1988Pigmentations and depigmentations, accompanied or not by yellow subretinal lipofuscin accumulations, are the ophthalmologically visible manifestations of dystrophies of the retinal pigment epithelium. The pigmentations may or may not become confluent and form concentric, butterfly-shaped or reticular configurations.
