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.

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

Tiny particles from stem cells help activate hair growth cells and encourage hair growth in mice without being toxic.

Applying a special compound can promote hair growth without harmful side effects.

Activating TRPV3 stops human hair growth.

The sebaceous gland has more roles than just producing sebum and contributing to acne, and new research could lead to better skin disease treatments.

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

The p75 neurotrophin receptor is important for hair follicle regression by controlling cell death.

All-trans retinoic acid causes hair loss by increasing TGF-β2 in hair follicle cells.

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.

Versican, a protein, is less present in thinning hair follicles and this decrease might contribute to common hair loss in men.

TNF family proteins are crucial for the development of skin features like hair, teeth, and mammary glands.

The Foxn1 gene mutation causes hairlessness and immune system issues, and understanding it could lead to hair growth disorder treatments.

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.

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

Feather growth and regeneration involve complex patterns, stem cells, and evolutionary insights.

Sericin hydrogels heal skin wounds well, regrowing hair and glands with less scarring.

Skin has specialized touch receptors that can tell different sensations apart.

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

Follistatin helps hair growth and cycling, while activin prevents it.

Mesenchymal stem cells show potential for skin healing and anti-aging, but more research is needed for safe use, especially regarding stem cells from induced pluripotent sources.

The conclusion is that certain scalp tissue changes are characteristic of lichen planopilaris, with mucinous perifollicular fibroplasia being a new feature for diagnosis.

LGR5 helps maintain corneal cell characteristics and prevents unwanted changes by controlling specific cell signaling pathways.

TRH stimulates human hair growth and extends the hair growth phase.

Exosomes from dermal papilla cells help hair growth by making hair follicle stem cells multiply and change.

Human hair follicles produce and respond to erythropoietin, helping protect against stress.

Sox2-positive dermal papilla cells have unique characteristics and contribute more to skin and hair follicle formation than Sox2-negative cells.

Hair growth can be induced by certain cells found at the base of hair follicles, and these cells may also influence hair development and regeneration.

Beta-caryophyllene helps improve wound healing in mice, especially in females.
