Accessory Structures of the Skin: Hair Growth and Types

Accessory Structures of the Skin: Hair Growth and Types

Hair growth begins with the production of keratinocytes by the basal cells of the hair bulb. As new cells are deposited at the hair bulb, the hair shaft is pushed through the follicle toward the surface. Keratinization is completed as the cells are pushed to the skin surface to form the shaft of hair that is externally visible. The external hair is completely dead and composed entirely of keratin. Hair can be cut or shaven without damaging the hair structure because the cut is superficial. Most...

Multipotency and Niche of Bulge Stem Cell

Multipotency and Niche of Bulge Stem Cell

A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...

Pigmentation

Pigmentation

The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

Cells of the Epidermis

Cells of the Epidermis

The epidermis is made of four or five layers of epithelial cells, depending on its location in the body. From deep to superficial, these layers are the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum.
The cells in all these layers except the stratum basale are called keratinocytes, a type of cell that manufactures and stores the protein keratin. The keratinocytes in the stratum corneum are dead and regularly slough away, being replaced by cells from...

Accessory Structures of the Skin: Hair and Hair Follicles

Accessory Structures of the Skin: Hair and Hair Follicles

Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet.
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...

Changes in Skin Color: Clinical Perspectives

Changes in Skin Color: Clinical Perspectives

The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Summary

Melanocyte stem cells (MSCs) in hair follicles maintain melanocyte function. Incomplete MSC maintenance leads to gray hair, impacting hair pigmentation.

Area of Science:

Developmental biology
Stem cell biology
Dermatology

Context:

Melanoblasts, the precursors of melanocytes, originate from the neural crest.
Melanoblasts migrate to hair follicles and differentiate into melanocytes, responsible for hair pigmentation.
Hair follicles harbor melanocyte stem cells (MSCs) that replenish differentiated melanocytes.

Purpose:

To elucidate the role of melanocyte stem cells (MSCs) in hair follicle pigmentation.
To understand the relationship between melanocyte activity and hair follicle cycling.
To identify the cause of gray hair formation.

Summary:

Melanocytes, crucial for hair color, originate from neural crest-derived melanoblasts.
Hair follicles maintain a population of melanocyte stem cells (MSCs) that are essential for producing functional melanocytes.

The activity and survival of melanocytes are intrinsically linked to the hair follicle's growth cycle.

Gray hair appears to result from inadequate maintenance of these vital melanocyte stem cells.

Impact:

Provides insights into the cellular mechanisms underlying hair graying.
Highlights the critical role of melanocyte stem cells in maintaining hair color.
Offers potential targets for future research into hair pigmentation disorders and age-related graying.
