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.

Hair follicles produce and respond to melatonin, affecting hair growth and sensitivity to estrogen.

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

The document concludes that while significant progress has been made in understanding skin biology and stem cells, more research is needed to fully understand their interactions with their environment.

The article concludes that the wool follicle is a valuable model for studying tissue interactions and has potential for genetic improvements in wool production.

Hair grows faster in the morning and is more vulnerable to damage from radiation due to the internal clock in hair follicle cells.

Hair loss occurs due to fewer papillary cells, smaller follicles, and shorter growth phases.

Ruby laser pulses best destroy hair follicles during the growth phase and effectiveness varies with laser intensity; melanin is key for targeting, and timing treatments can improve results.

Liposomes could improve how skin care products work but are costly and not very stable.

Melatonin helps regulate hair growth and protects the hair follicle from stress.

Researchers found that hair shedding happens mostly when new hair is growing and involves a unique process.

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

We need more research to better understand human hair follicle stem cells for improved treatments for hair loss and skin cancer.

Hirsutism is more linked to high androgen levels than acne or hair loss, and a mix of hormonal tests is best for diagnosis; certain treatments can reduce symptoms.

Treating psoriasis on the scalp, nails, and skin folds is challenging, often requiring systemic treatments for severe cases, with some success in topical and biologic treatments.

Male pattern hair loss is genetic and influenced by hormones, with treatments like minoxidil and surgery available.

Laminin-511 is crucial for early hair growth and maintaining important hair development signals.

Male hormones and their receptors play a key role in hair loss and skin health, with potential new treatments being explored.

Growth factors and cytokines are important for hair growth and could potentially treat hair loss, but more research is needed to overcome challenges before they can be used in treatments.

Scientists created stem cells that can grow hair and skin.

The document concludes that certain genetic mutations and dietary factors are involved in acne development, and treatments like isotretinoin and diet changes can help manage it.

Hair ages due to genetics and environmental factors, leading to graying and thinning, with treatments available for some conditions.

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

No treatment fully prevents hair loss from chemotherapy yet.

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

Trichoscopy is a useful, non-invasive way to diagnose different types of hair loss.

Grafted rodent and human cells can regenerate hair follicles, but efficiency decreases with age.

EGF makes hair follicles grow longer but stops hair production.

The document concludes that accurate diagnosis of different types of hair loss requires careful examination of hair and scalp tissue, considering both clinical and microscopic features.
