The pigment cells
are dominated by very densely staining granules, which surround a moderate to densely staining ovoid cytoplasm and nucleus (Figs.
Yoshida and her co-workers studied blue dayflowers, cornflowers, and salvia, which are blue despite the fact that the pigment cell
sap of their petals is weakly acidic.

Melanoma is a cancer of the pigment cells
in our skin.
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.
They consist of no more than two cells: a photoreceptor cell and a pigment cell
Objective: Melanoma tumours develop in the pigment cells
located in the skin.
The drug, which can only be injected with needles, is a synthetic hormone designed to stimulate pigment cells
to produce more melanin, which gives you a tan when exposed to UV rays.
The increase in the efficiency was only 8% in pigment cells
Neural crest cells migrate to different parts of an embryo and give rise to several tissues, including the bone and cartilage that shape faces, muscles, pigment cells
and the adrenal glands, which control the flight-or-fight response.
The research, published in Nature, revealed that UV light directly damages DNA in the skin's pigment cells
, which increases the chance of developing the disease.
