Sentences with phrase «produces hair cells»

Most of the internal structure of a hair is made from collagen, which ultimately produces hair cells.

Not exact matches

Cells called melanocytes produce the pigments that colour hair and their numbers are kept topped up by stem cCells called melanocytes produce the pigments that colour hair and their numbers are kept topped up by stem cellscells.

A few years ago, biologists discovered that some produce hair - like filaments that act as wires, ferrying electrons back and forth between the cells and their wider environment.

Heller's team produced the inner - ear hair cells by exposing embryonic cells in the lab to chemical factors which steer the natural development of hair cells.

In the recessive deafness model, gene therapy with TMC1 restored the ability of sensory hair cells to respond to sound — producing a measurable electrical current — and also restored activity in the auditory portion of the brainstem.

«However, once the dermal papilla cells are put into conventional, two - dimensional tissue culture, they revert to basic skin cells and lose their ability to produce hair follicles.

For example, in both the blood - cell - producing and the hair - follicle niches, different stem cell types need to coordinate their individual production.

The researchers say such «hypopigmentation» occurs because chloroquine poisons pigment - producing cells in hair follicles.

But hair growth depends on the ability of cells in the hair follicles to keep dividing and so producing cells which die and are built into the hair shaft.

Without KROX20 - producing cells, no hair grew, the study said.

What they did not know in detail is what happens after those stem cells move down to the base, or bulb, of hair follicles and which cells in the hair follicles produce SCF — or that cells involved in hair shaft creation make the KROX20 protein, he said.

When they deleted the KROX20 - producing cells, no hair grew and the mice became bald, according to the study.

If cells with functioning KROX20 and SCF are present, they move up from the bulb, interact with pigment - producing melanocyte cells, and grow into pigmented hairs.

One produces pigment for the hair before dying off, while the other becomes a new melanocyte stem cell.

The cells produced more eumelanin, the pigment responsible for black and brown skin, hair, and eyes.

Mice that produced the extra Atoh1 had almost twice as many hair cells as did control mice, the researchers report today in Nature.

Jian Zuo, Ph.d., and his colleagues induced supporting cells located in the inner ear of adult mice to take on the appearance of immature hair cells and to begin producing some of the signature proteins of hair cells.

By manipulating the same genes, Zuo and his colleagues induced supporting cells located in the inner ear of adult mice to take on the appearance of immature hair cells and to begin producing some of the signature proteins of hair cells.

The epithelial stem cells, when implanted into immunocompromised mice, regenerated the different cell types of human skin and hair follicles, and even produced structurally recognizable hair shaft, raising the possibility that they may eventually enable hair regeneration in people.

The group recently produced data showing that stem cells from human hair follicles also differentiate into contractile smooth muscle cells.

They conducted a study in mice and found that the stem cell that produces all the different cells of the skin actually lives in hair follicles.

Setae, hair - like structures produced by cells on the wing blade, were used to infer changes to cell size and number.

Melanocytes are cells that produce the melanin pigment visible in skin and hair coloration.

The cells are held close to the base of the epidermal derived cells that produce the hair fiber and root sheaths but there is a thin layer, called the basement membrane (or basement lamina, or glassy membrane) that separates the DP cells from the hair fiber / sheath cells.

When a hair follicle is not producing a fiber the DP cells lose much of their cytoplasm and become inactive.

With each renewed attempt to produce hair fiber, the hair follicle must obtain a source of cells to form the matrix cell population that make hair fibers.

The bigger the DP, the more cells it has, then the thicker the hair fiber that the hair follicle produces.

Nourishing cell function through sweet potatoes helps produce scalp oils that lead to stronger and more vibrant hair.

In acne, skin cells produce too much keratin, a protein that's the key structural component of your skin, hair and nails.

Free radicals damage hair and melanin producing cells thus contributing to the premature greying of the hair.

Glutamate is a neurotransmitter, produced by the action of sound waves on the hair cells of the inner ear.

Just think of the volume of snot that is produced, the volume of ejaculate, the volume of hair, fingernails, skin cells,... it gets stupid, really!
