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

TPA promotes hair growth by increasing stem cell activity and activating specific cell signals.

PBX1 helps hair stem cells grow and change by turning on certain cell signals and preventing cell death, which may be useful for hair regrowth treatments.

Malva verticillata seed extract might help treat hair loss by activating hair growth signals in skin cells.

Estrogen is important for keeping adult mouse nipple skin healthy by controlling certain cell signals.

Testosterone can both promote hair growth and cause baldness by affecting hair growth signals.

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.

Collagen makes skin stiff, and preservation methods greatly increase tissue stiffness.

Hair follicle stem cells are important for maintaining healthy skin and interact with many signals.

Different people show different symptoms for genetic diseases because of how sensitive their bodies are to small changes in important factors.

Activin B improves wound healing and hair growth by helping stem cells move using certain cell signals.

Ginsenoside F2 from ginseng may increase hair growth better than standard treatments by affecting cell growth signals.

Linoleic acid from Malva verticillata seeds may help treat hair loss by promoting hair cell growth and blocking baldness signals.

Newly divided skin cells quickly move to join skin structures due to tissue tension and specific signals.

Different ectodermal organs like hair and feathers regenerate differently, with specific stem cells and signals involved in their growth and response to the environment.

The document concludes that more research is needed to better understand and treat primary cicatricial alopecias, and suggests a possible reclassification based on molecular pathways.

The study found that a specific area of the hair follicle helps start hair growth by reducing the blocking effects on certain cells and controlling growth signals.

New hair can grow from large wounds in mice, but less so as they age, involving reprogramming of skin cells and specific molecular pathways.

Ginsenoside Rg4 from ginseng may help hair growth by activating certain cell signals.

ILK is essential for proper hair follicle development and structure.

Wnt-3a helps grow more skin stem cells, which could lead to new hair loss treatments.

Stem cell niches are crucial for regulating stem cell renewal and differentiation, and understanding them can help in developing regenerative therapies.

The Sonic hedgehog pathway is crucial for new hair growth during mouse skin healing.

New treatments targeting skin stem cells show promise for skin repair, anti-aging, and cancer therapy.

Rare adrenal cancers that secrete androgens or estrogens have a poor prognosis and are treated primarily with surgery.

Old people have less hair because their hair follicles don't regenerate as well, not because of fewer stem cells, and a protein called follistatin might help reactivate hair growth.

Different types of stem cells with unique roles exist in blood, skin, and intestines, and this variety is important for tissue repair.

TGF-β signaling is crucial for stem cell maintenance, differentiation, and has implications for cancer treatment.

Mice hair growth patterns get more complex with age and can change with events like pregnancy or injury.

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