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

Understanding hair growth involves complex factors, and more research is needed to improve treatments for hair loss conditions.

Hair loss and aging are caused by the breakdown of a key protein in hair stem cells.

The we/we wal/wal mice have defects in hair growth and skin layer formation, causing hair loss, useful for understanding alopecia.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

Tissue engineering could be a future solution for hair loss, but it's currently expensive, complex, and hard to apply in real-world treatments.

The study found new details about human hair growth and suggests that preventing a specific biological pathway could potentially treat hair graying.

MicroRNAs are important for hair growth regulation, with Dicer being crucial and Tarbp2 less significant.

Notch signaling is essential for healthy skin and hair follicle maintenance.

Dermal cells are key in controlling hair growth and could potentially be used in hair loss treatments, but more research is needed to improve hair regeneration methods.

Exposure to 50 Hz electromagnetic fields may help mice grow hair faster.

Overexpression of sPLA2-IIA in mouse skin reduces hair stem cells and increases cell differentiation through JNK/c-Jun pathway activation.

New treatments for skin damage from UV light using stem cells and their secretions show promise for skin repair without major risks.

Dlx3 is essential for hair growth and regeneration.

Wnt signaling controls whether hair follicle stem cells stay inactive or regenerate hair.

The Msi2 protein helps keep hair follicle stem cells inactive, controlling hair growth and regeneration.

Certain transcription factors are key in controlling skin stem cell behavior and could impact future treatments for skin repair and hair loss.

Understanding how melanocyte stem cells work could lead to new treatments for hair graying and skin pigmentation disorders.

Removing integrin α3β1 from hair stem cells lowers skin tumor growth by affecting CCN2 protein levels.

Skin stem cells remember past inflammation, helping them respond better to future injuries and possibly aiding in treating skin issues.

Hair growth phase and certain genes can speed up wound healing, while an inflammatory mediator can slow down new hair growth after a wound. Understanding these factors can improve tissue regeneration during wound healing.

Disrupted stem cell signals in hairpoor mice cause hair loss.

Activating TRPV4 in skin cells helps regrow hair in mice, possibly offering a treatment for hair loss.

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

Stem cells from hair follicles can safely treat hair loss.

Photodynamic therapy can remove nonpigmented hair in mice and might work for humans.

Nanocarriers with plant extracts show promise for safe and effective hair growth treatment.

The review found that different stem cell types in the skin are crucial for repair and could help treat skin diseases and cancer.

Mutations in the Vitamin D receptor gene can cause hair loss similar to mutations in the Hairless gene.

Human sebaceous glands can grow back in skin grafts on mice and work like normal human glands.
