Behavior of
pigment cells closely correlates the manner of gastrulation in sea urchin embryos.
In the pleopod photophore, the processes of the reflecting
pigment cells form a common cap around the apex of the complete set of photocytes [ILLUSTRATION FOR FIGURES 24 AND 25 OMITTED]; in contrast, in the photophores of the maxilliped, each individual photocyte has its own cap of reflecting
pigment cell processes.
Abnormalities in
pigment cells can affect us in many ways, from genetic disorders such as albinism to freckles caused by aging.

Regarding the number of
pigment cells in each stage, females in mid pregnancy exhibited a higher number of pigmented cells, followed by females in late pregnancy and early pregnancy.

Following an introduction to development of
pigment cell lineage, they discuss the basis of specific coloration patterns.
(5) In September 2008, three reviews were published in the medical journal
Pigment Cell and Melanoma Research that highlighted the huge amount of evidence linking tanning salons and melanoma.
The preretinal and postretinal membranes correspond to the basal laminae of the lentigen layer, retina and
pigment cell layer.
