pigment cell

His skin is lacking pigment cells or something like that.

In severe cases, all the pigment cells are lost.

There are up to 200 of these special pigment cells per square millimeter.

Some have pigment cells which move across the light detectors during the day, shielding them.

As hair pigment cells decline in number, gray hair growth increases.

With aging, pigment cells die, and hair turns gray.

The pigment cells line the outside of each ommatidium.

Pigment cells help block damaging ultraviolet light from penetrating the skin.

The skin is similar to areas elsewhere, but is relatively thin and has more pigment cells.

The pigment cells reside in a narrow band along the shell's lip.

It is due to uncontrolled growth of pigment cells, called melanocytes.

It is a chemical reaction involving melanin pigment cells in the skin.

But it turns out, each mole is a tumor of pigment cells that started on a path to cancer and then stopped.

Its enhanced pigment cells can alter color and pattern to instantly match any background.

Skin color is produced via pigment cells called chromatophores.

Some cells migrate beneath the future skin and will give rise to pigment cells.

Young skin is not only thinner but also has fewer pigment cells and is less able to protect itself from the sun.

Hair pigment cells become less efficient at renewing themselves, which makes hair gray.

The pigment cells, called chromatophores, are derived from the neural crest.

One hypothesis is that the body's immune system turns on melanocytes, the skin's pigment cells, destroying them.

Hence, the pigment cells pump out only gold-bronze colors.

This is because at low light levels, heat affects the pigment cells as much as light.

The super chilled marker kills the pigment cells in the hair, which then grow back white to show a distinct code.

There are pigment cells that are distributed throughout the cortex, giving the hair its characteristic color.

Dominant white horses do not have pigment cells, and thus no pigment, in the skin or coat.
