Stress can stop hair growth in mice, and treatments can reverse this effect.

Stem cell plasticity is crucial for wound healing but can also contribute to cancer development.

Dexamethasone speeds up hair loss in mice, while cyclosporin A slows it down.

Smoking harms the skin, causing early aging and increasing cancer risk, but stopping smoking can improve skin health.

Wnt and Notch signaling help wound healing by promoting cell growth and regulating cell differentiation.

The document concludes that hair is complex, with a detailed growth cycle, structure, and clinical importance, affecting various scientific and medical fields.

PDGFA/AKT signaling is important for the growth and maintenance of certain skin fat cells.

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.

Hair follicles are hormone-sensitive and involved in growth and other functions, with potential for new treatments, but more research is needed.

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

The Wnt/β-catenin pathway helps tissue regeneration but can also cause fibrosis, and drugs that inhibit this pathway may aid in healing skin and heart tissues.

EGF makes hair follicles grow longer but stops hair production.

Mouflon rams mature gradually with changes in body, horns, and hormones linked to age and seasons, reaching full sexual maturity well after puberty.

The document concludes that understanding the genes and pathways involved in hair growth is crucial for developing treatments for hair diseases.

Using human fat tissue derived stem cells in micrografts can safely and effectively increase hair density in people with hair loss.

Activating the Wnt/β-catenin pathway could lead to new hair loss treatments.

The skin protects the body and is constantly renewed by stem cells; disruptions can lead to cancer.

The conclusion is that tissue structure is key for stem cell communication and maintaining healthy tissues.

Activin helps skin growth and healing mainly through stromal cells and affects keratinocytes based on its amount.

Muscles and nerves that cause goosebumps also help control hair growth.
