Reductive stress messes up collagen balance and alters cell signaling in human skin cells, which could help treat certain skin diseases.

UV exposure reduces Lgr6+ stem cells in mouse skin and they don't significantly contribute to skin cancer development.

Cell-based models help test if cosmetic ingredients really work for hair growth and skin health.

A protein called PCBP2 controls the production of a hair growth protein by interacting with its genetic message and is linked to hair loss when this control is disrupted.

Removing Dicer from pigment cells in newborn mice causes early hair graying and changes in cell migration molecules.

External factors can cause skin cancer cells that usually don't spread to grow and form tumors in mice.

Exosomes from stem cells may help rejuvenate skin and regrow hair, but more research is needed.

GPR39 is linked to certain cells in the sebaceous gland and helps with skin healing.

Honokiol helps protect skin from damage and aging caused by cigarette smoke.

Ptprq has multiple forms that change during inner ear development.

β-catenin is essential for stem cell activation and proliferation in hair follicles.

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

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

Prominin-1 expressing cells in the dermal papilla help regulate hair follicle size and communication but don't aid in skin repair.

Artificial skin development has challenges, but new materials and understanding cell behavior could improve tissue repair. Also, certain growth factors and hydrogel technology show promise for advanced skin replacement therapies.

Early-stage skin cells help regenerate hair follicles, with proteins SDF1, MMP3, biglycan, and LTBP1 playing key roles.

Collagen and TGF-β2 help maintain hair cell shape and youthfulness.

Hair dye ingredient PPD causes cell death and aging in human hair cells by altering microRNA levels.

Valproic Acid helps regrow hair in mice and activates a hair growth marker in human cells.

Wnt10b overexpression can regenerate hair follicles, possibly helping treat hair loss and alopecia.

Wnt3a activates certain genes in hair follicle cells, including a newly discovered one, EP2, which may affect hair growth.

Adult stem cells with Tp63 can form hair and skin cells when placed in new skin, showing they have hidden abilities for skin repair.

Wnt1/βcatenin signaling is crucial for heart repair after injury.

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

Noggin is necessary to start the hair growth phase in skin after birth.

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

Skin-derived precursors in hair follicles come from different origins but function similarly.
