Summary
Melanocyte stem cells in the hair follicle bulge are crucial for hair color. Their loss is a primary cause of hair graying, highlighting the need for further research into their differentiation mechanisms.
Area of Science:
- Dermatology
- Cell Biology
- Genetics
Background:
- Hair graying is a common phenomenon associated with aging.
- Melanocytes are responsible for hair pigmentation.
- Melanocyte stem cells (MSCs) reside in the hair follicle bulge.
Purpose of the Study:
- To investigate the relationship between MSCs in the hair follicle bulge and hair graying.
- To elucidate the role of MSCs in the pathogenesis of hair graying.
Main Methods:
- A literature search was conducted on PubMed.
- Keywords included "hair graying," "hair color," "pigmentation disorders," "melanocyte stem cells," and "melanocyte."
- Published articles were analyzed to explore the relationship between MSCs and hair graying.
Main Results:
- Both melanocytes in the hair bulb and MSCs in the hair follicle bulge are involved in hair graying.
- MSCs play significant roles in the development of hair graying through various mechanisms.
Conclusions:
- The loss of MSCs in the hair follicle bulge is a major contributor to hair graying.
- Further research is required to understand the mechanisms of ectopic differentiation of MSCs.

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...

01:20Accessory Structures of the Skin: Hair Growth and Types
1.5K
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...

In humans, the photoreceptor cells of the eye and sensory hair cells of the ear lack stem cells. These cells are thus unrenewable and cannot be replaced when they are damaged or destroyed.
Photoreceptors
The retina is composed of several layers and contains specialized cells called photoreceptors. The photoreceptors (rods and cones) change their membrane potential when stimulated by light energy. There are two types of photoreceptors—rods and cones—which differ in the shape of...

01:12Renewal of Skin Epidermal Stem Cells
2.6K
The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular...

01:19Pigmentation
2.5K
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...

01:19Multipotency of Hematopoietic Stem Cells
3.2K
The hematopoietic stem cells or HSCs are multipotent, meaning they can differentiate and give rise to all blood and immune cells. HSCs are maintained in the quiescent stage until an external stimulus initiates their differentiation. The multipotent HSCs exist as two heterogeneous populations, long-term repopulating cells (LTRC) and short-term repopulating cells (STRC). The two HSC populations have different surface markers or receptors and are classified based on quiescence and long-term...
