Manga, "On the etiology of contact/occupational vitiligo," Pigment Cell
A few cells of unknown function are found between the basal lamina of the pigment cells
and the basal lamina surrounding the retina.
The number of supporting pigment cells
forming the screening pigment cup can be as many as six in Spirobranchus corniculatus to none in the Protula unpigmented receptor.
signalling for physiological color change.
In sea urchin larvae, the skeletogenic mesenchyme cells (4), pigment cells
(6), and muscle cells (7) are derived from mesodermal cells, and spatiotemporal and temporal-numeric studies of pigment cells
have been conducted in a variety of sea urchin species (8-11).
In pigment cells
, NO causes aggregation in amphibian melanophores (Nilsson et al.
Melanoma is a cancer of the pigment cells
in our skin.
The inset of Figure 2D shows a section through another eye in which two back-to-back, labeled pigment cell
cups form an incomplete "H" as they extend arms around two groups of photoreceptors (Takenaka et al.
We speculate that nitric oxide may act as a negative regulator of pigment cell
division and skeletal extension in vivo.
The study found that a protein called RXR-alpha in skin keratinocytes appears to protect pigment cells
from damage, and prevent them from progressing to invasive melanoma.
