Hair growth is cyclic and influenced mainly by local factors.

Changing the environment around stem cells could help tissue repair, but it's hard to be precise and avoid side effects.

African spiny mice can regenerate skin, hair, and cartilage, but not muscle, and their unique abilities could be useful for regenerative medicine.

Nerve signals are crucial for hair follicle stem cells to become skin stem cells and help in wound healing.

Frontal fibrosing alopecia is a hair loss condition in postmenopausal women, similar to lichen planopilaris, with ineffective treatments.

Lichen Planus is a less common condition affecting skin and mucous membranes, with various types and associated risk factors, challenging to diagnose, significantly impacts life quality, and may have a risk of cancerous changes in oral lesions.

The study found that sweat glands contain different types of stem cells that help with healing and maintaining healthy skin.

Cells from balding scalps have more androgen receptors than cells from non-balding scalps.

Two main types of fibroblasts with unique functions and additional subtypes were identified in human skin.

Androgens can both increase and decrease hair growth in different parts of the body.

Stem cell niches are crucial for regulating stem cell renewal and differentiation, and understanding them can help in developing regenerative therapies.

Epigenetic changes control how adult stem cells work and can lead to diseases like cancer if they go wrong.

Epidermal stem cells are diverse and vary in activity, playing key roles in skin maintenance and repair.

Stem cell niches support, regulate, and coordinate stem cell functions.

Some people with pattern hair loss may also have scalp inflammation and scarring similar to lichen planopilaris.

Lichen planus is a skin condition that can resolve on its own, is linked to hepatitis C, and increases the risk of skin cancer.

Stem cell self-renewal is complex and needs more research for full understanding.

The document concludes that a better understanding of cell changes during wound healing could improve treatments for chronic wounds and other conditions.

Sonic hedgehog signaling is crucial for hair growth and maintaining hair follicle identity.

Different types of stem cells with unique roles exist in blood, skin, and intestines, and this variety is important for tissue repair.

Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.

Different types of stem cells and their environments are key to skin repair and maintenance.

The document concludes that specific cells are essential for hair growth and more research is needed to understand how to maintain their hair-inducing properties.

Cytokeratin 19 and cytokeratin 15 are key markers for monitoring the quality and self-renewing potential of engineered skin.

Hair, teeth, and mammary glands develop similarly at first but use different genes later.

The document concludes that assessing hair follicle damage due to cyclophosphamide in mice involves analyzing structural changes and suggests a scoring system for standardized evaluation.

Androgens can both stimulate and cause hair loss, and understanding their effects is key to treating hair disorders.

The document concludes that adult mammalian skin contains multiple stem cell populations with specific markers, important for understanding skin regeneration and related conditions.

Mammals might fail to regenerate not because they lack the right cells, but because of how cells respond to their surroundings, and changing this environment could enhance regeneration.

Skin development in mammals is controlled by key proteins and signals from underlying cells, involving stem cells for maintenance and repair.
