Understanding gene expression in hair follicles can reveal insights into hair growth and disorders.

The document concludes that the hair cycle is a complex process involving growth, regression, and rest phases, regulated by various molecular signals.

Basal cell carcinoma mostly starts from cells in the upper skin layers, not hair follicle stem cells.

The skin has a complex immune system that is essential for protection and healing, requiring more research for better wound treatment.

The circadian clock affects skin stem cell behavior, impacting aging and cancer risk.

The document concludes that mouse models are helpful but have limitations for skin wound healing research, and suggests using larger animals and genetically modified mice for better human application.

The document likely offers guidance on treating a woman's excessive hair growth, considering her symptoms and obesity.

Medium-sized particles penetrate hair follicles better than smaller or larger ones, which could improve delivery of skin treatments.

Understanding where cancer cells come from helps create better prevention and treatment methods.

Scientists have found a way to create hair follicles from skin cells of newborn mice, which can grow and cycle naturally when injected into adult mouse skin.

Shorter CAG repeats may cause hair and skin issues, while longer ones may link to acne.

Hormone treatments in transsexual individuals reduce hair growth and oil production in male-to-females and increase them in female-to-males.

Telocytes might help with skin repair and regeneration.

Laser hair removal effectiveness depends on targeting hair structures without harming the skin, and improvements require more research and expert collaboration.

Aging causes skin stem cells to work less effectively.

EGFR inhibitors often cause skin problems and other side effects, but these are usually reversible and can be managed to keep patients comfortable.

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.

Human hair follicle organ culture is a useful model for hair research with potential for studying hair biology and testing treatments.

Estrogen Receptor ß (ERß) is the main hormone controller in human skin and hair follicles, not Estrogen Receptor α (ERα) or the Androgen Receptor (AR).

Damage to skin releases dsRNA, which activates TLR3 and helps in skin and hair follicle regeneration.

Prolactin contributes to hair loss by promoting hair follicle shrinkage and cell death.

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

The hydrogel with a 1:3 ratio of hydroxyethyl cellulose to hyaluronic acid is effective for delivering drugs through the skin to treat acne.
